The
SAILOR
MAN
3 Screens-Plus-'INVISO SCR66N"
The First
64K Arcade Game
For the Color Computer
The first screen objective is to catch enough of Elsie's kisses
(those Red Heart Shaped Things) to fill in the squares on
the Sailorman's house. If you can time your punch just so,
you can send the punching bag over to knock the bucket
down and, with a little bit of luck, right onto Bigfatbadguy's
head. This will give you a little (but not much) time to catch
all those RHSTs.
You must avoid contact with Bigfatbadguy who is actively
pursuing you. You must also be careful of Olduglysea-
woman who will appear at higher difficulty levels to chuck
empties at you. Either avoid the flying bottles or punch
them (with the fire button) to keep from being knocked into
the water.
The second screen objective is to collect enough notes to
play Elsie a little love song. You may jump off and onto the
other end of Fatguyeatingahamburger's teetertotter to fly
up a deck and even two decks if you manage to catch
hold of Smartaleckkid's grab handles. Time it right and
away you go.
The Third screen objective is to collect enough letters
(thrown by Elsie's cries for H-E-L-P) to complete a ladder all
the way to the crow's nest where Elsie is calling you. Beware
of the Crow, however, who thinks you are after her eggs!
On all screens, eating a can of collard greens (labeled
"S" for Collard and grasped by punching the can just right)
will give you amazing speed, strength and agility and
allow you to send Bigfatbadguy into the drink with a single
punch.

Better Than Aspirin
Editor:
I have discovered a simple way to defeat
the head banger bug in Disk basic.
I ) Turn the computer on. but not the disk
drive.
2)TypeDIR.
3) Wait approximately 4.5 seconds after
you hit ENTER and press Reset.
4) Turn the disk drive on.
This trick will increase the life of your disk
drive.

Richard Gains' hint (September rain-
bow. Page I06) checks whether your printer
is on or off line. II I could remember to check
belore I'm all loaded to print, there would be
no problem. Ever since I saw something like
the following in a program of Jorge Mir's,
I've been wedging this into any applicable
program. I can turn on the printer and still
have some switch off. so what looks like
repetition is. It keeps throwing back "not
ready" until the printer reallv is ready.

Stepping Up
Editor:
If your readers have a Radio Shack disk
controller and drive, they can poke two
addresses to change the stepping rate after
they've entered memorv map I (64K RAM).
POKES 55232.2 and 55318.22 will change
the stepping rate to 20 ms. The benefits are
really noticeable with disk intensive pro-
grams like Disk Graphics.

Editor:
I would like to share with your readers the
following discoveries I have made of Elite
Word (Disk basic) and Elite Pile.
1) To change the Elite File top margin
(TM) default to zero, so output file can be
merged with Elite Word, add the following
line in the basic driver (F1LE.BAS):
142 POKE&HID5I.&H0
2) Elite Word generated &H6 for printer
form feed. For most printers, such as OKI-
DATA 82A. the form feed ASCII code is
&HC. To solve this incompatibility prob-
lem, add the following lines in the basic
driver (EW64.BAS}.
231 POKE&H6072.&H0C
232 POKE &H6959.& HOC

Editor:
Something I discovered while writing a
program that sorts by a string of numbers
embedded in the front of each information
string. The function "STR$(numeric)",
which converts numeric expression to a
string also adds a space (ASCII 32) in front
of the string. To eliminate the space 1 used
this line:
N$=STR$(X):NS=R1GHT$(NS.I)
I only needed one number in this portion
of my program, but if X was to be varying
lengths then "LENS(str)" could be used in
"RIGHTS":
N$=RIGHTS(NS.(LEN(N$)-D)
works fine, i hope this little tidbit will help
someone in their programming.

Putting On The Switch
Editor:
While at RAINBOWfest I purchased a
copy of GRAPH/COM. While reading
through the documentation for this fine
piece of graphics software 1 had an idea on
how to get around the problem of holding
down two fire buttons on your joysticks and
at the same time moving the cursor around
the screen. Radio Shack has a switch (part
number 275-617) that is identical to the fire
button but is a SPST Push On Push Off
switch. This could be soldered into the joy-
stick in place of the existing fire buttons or
any mini SPST Push On Push Off switch
could be mounted into the case of the joy-
stick. This would solve the problem of need-
ing three hands to operate this particular
piece of software.

Editor:
We recently received a TDD (telecom-
munications device for the deal") for my step-
son and I would like to hook this up through
my TRS-80 Color Computer 2 so that a
preset-up message might be transmitted
through the TDD at a quicker speed than he
is capable of typingon thcTDD keyboard. 1
realize that this could be done through a
recorder; however, this would not affect the
speed as it would still play through at the
same speed as it was typed.
The programming is not the problem but
it is in hardware hook-up. and I thought one
of the readers might have solved the same or
similar problem. The TDD is a Minicom II
manufactured by Ultraiec.
If you have any answers, please write me
at 1491 Old Kings Road. 32017.

Editor:
I have a few questions you may be able to
answer. I just finished typing in a utility 1
found in your February 1984 issue (Page
188) and it doesn't seem to work. No errors
were found and 1 checked over my listing
very carefully. (I list them to my printer).
However, the program always seems to lock
up. 1 had to use the start location of 3F00 as
the assembler would not take it on my 32K
piggyback CoCo. Is that why it locks up:
because I have a piggyback system?
Steven Spice
Toronto, Ontario
Editor's Note: That is the only thing 1
would suspect. Try installing 64K
RAMs.
Editor:
I have a Model 33 Teletype and I've built
the interlace from an article in the February
1983 issue [Page 1 18] of the rainbow, but.
after months of hacking with it. I haven't
been able to get the teletype to respond as a
printer.
Among the questions that come to mind
are:
I) How do I check whether the TTY is
running with a .020 or .060 Amp loop? (I
measured .063 Amps across terminals No. 2
and No. 8 on SMDcard.)

2) At what point on the SMD card should
the connections be made?
Frank J. Chiacchio
Bensalem, PA
Editor's Note: I had a Model 35 so the
SMD card was probably different. I
think the Model 33 already has a
built-in loop supply so just the 4N33 is
necessary. Key the loop with the
switching transistor in the 4N33.
Sorry I cant be more specific but I
dont have a Model 33.
Checkers And Chess
Editor:
1 recently bought a TRS-80 CoCo 2 with
Extended basic and I don't know how to
make programs. I would like to get a pro-
gram list for a checker game and also a chess
game. If anyone knows of such a game,
please let me know so I can order them.
I would like to add that rainbow is the
best magazine I have read for the CoCo
owner. My address is 742 Davis Street,
27288.

Has anyone heard of where I can get a
replacement ribbon for my Impact Data
printer? It's a very obscure brand of printer,
and it requires a three-foot loop of ribbon
'A" wide. I have checked inside a DMP-1 10
ribbon cartridge and it was much too short.
Do any of the other Radio Shack printers
have a longer ribbon?

Always number in increments of 10 start-

You and your staff are to be compli-
mented for the effort associated with the

I would like to say a few kind words about
one of your advertisers. In July 1 ordered a
Gemini-lOX printer from Dayton Associ-
ates, Inc., and was pleasantly surprised by
their prompt and courteous service. I order-
ed the printer C.O.D. by phone on Monday
and received it the following Friday. I would
not hesitate to order any product from them
again. Thanks Dayton, I am enjoying my
printer.

Sometimes I read and write letters de-
scribing horrible experiences with computer
dealers. I thought your readers would like to
know of the wonderful service I've had from
one of your advertisers, Computerware of
Encinitas, Calif.
I ordered one of their green screen moni-
tors, tried it, but found that in the Hi-Res
mode it had a little too much contrast for my
liking. After a couple of weeks, I exchanged
it for an amber monitor, thinking that would
make things better, but 1 still had the same
problem. Eventually I had to return the
monitor for a refund, which was promptly
issued.
The point here is not that the monitor was
not to my liking, but that Computerware
stood behind their guarantees 100 percent,
the people 1 dealt with were always helpful; a
genuine effort was made to get my system
working the way 1 wanted, and 1 was never
given an argument.

Editor:
I am writing to you with details of a new
national user group for the Dragon/ Tandy
computer, based in Europe. As I am sure
you are aware. Dragon Data, the company
that made and sold the Dragon, has ceased
to exist. However, things are far from
gloomy for Dragon users.
First of all, the Dragon Computer will
continue to be made (in Spain) by a com-
pany called Eurohard, who will also be
responsible for worldwide distribution. Uni-
ted Kingdom sales, distribution and serv-
icing will be handled by GEC and a new
company has been formed (from the ashes of
Dragon Data) called "Touchmaster," that
will be responsible for customer support and
software development.
A new national users club has been set up
to replace that previously run by Dragon
Data. It has the official backing of "Touch-
master" ex-Dragon Data. Our main aim is to
get the 6809 better publicity in the computer
press and to provide a forum for exchange of
ideas, etc. I would be grateful if you would
publish details of this new club, further
information available on request. Write to:

Some good news and some bad news this month . . . followed by some more
good news.
One of the most innovative projects which has hit the computer marketplace this
year has been Radio Shack's series of Personal Computer Showcases in five cities
across the U nited States during September and October. These showcases played to
good crowds in Houston. Atlanta, Los Angeles, New York and Chicago, and
offered an awful lot of people an opportunity to see what Radio Shack has to offer
in the way of computer hardware and software.
What was unique — at least for Radio Shack — was that third party vendors
were not only allowed to participate, but made up the bulk of the people with
products on display. And, friends, it really did do my heart good to see some of the
"giants"of the industry — Small Computer Company, Lotus. MicroPro, IUS and
the like — among those who chose to exhibit.
One of the reasons the Personal Computer Showcases were so unusual was
because there was no fee to exhibit. That certainly did not mean exhibiting was free
— after all, the majority of the expense for a show is not in the space rental. Yet,
Radio Shack went out of its way to encourage as many firms as possible to
participate in the Showcases — even to arranging discount air fare and hotel
rooms!
We were proud that T HE RAINBOW was able to participate in all five Showcases
(along with its sister publication PCM). And. while only one software firm partici-
pated in all five Showcases, there was a good regional representation by other
companies at each show. Radio Shack also had its own CoCo booth! We went to
the Showcases because we believed it was important to support this effort by Radio
Shack, but. also, because it gave us an opportunity to tell literally thousands about
our favorite machines and the publications we produce. Our participation in the
Showcases has already resulted in additional subscriptions for THE RAINBOW.
Aside from that, how did the Showcases do? 1 must reflect on the two shows that I
recently attended in Los Angeles — Comdex and the National Software Show.
Radio Shack's Personal Computer Showcase in LAoutdrew both of these "name"
shows — and may have had more than both combined.
Admittedly, both Comdex and NSS were less than successful. And, while our
own RAINBOWfest drew more last year in Long Beach, there were reasons for
that. RAINBOWfest was on a holiday weekend (it will be this year in Irvine, too)
and wasn't in the downtown area. As I said. Radio Shack can be proud of its
"showing" at the shows. Crowds were good at all the other shows, too.
Our inside information is that there will be more Radio Shack Personal Compu-
ter Showcases, perhaps as soon as the Spring. Based on the success of these five, it
would not surprise me if five more were in the offing. If one comes toyourarea, by
all means attend. And drop by our booth to say "hello." If Radio Shack has another
show, we'll be there!
My congratulations go to Mark Hulsizerand Phil Kitchen, who were the driving
forces behind these Showcases. And, says my inside information, it was Board
Chairman John Roach, himself, who came up with the idea. A good one, John.
Moreover, Radio Shack has once again disproved its critics who say that they
oppose third party products in their field. Do you see other computer firms
spending what must have been hundreds of thousands of dollars to showcase their
products along with third party vendors? I think not.
On the bad news front, we are forced to announce an increase in subscription
price, effective Jan. 1 , 1 985. There are two reasons for the increase: The two biggest
P's of publishing — paper and postage.
No doubt you have read that second class postage rates will go up the first of the
year by some 16 percent. At the same time, paper prices have increased (or will
increase by January 1) some 17 percent. This represents a substantial increase in
what it costs us to deliver THE RAINBOW to you.
So. beginning Jan. I, 1985, the regular one year subscription price for THE
RAINBOW will increase by $3, to $3 1 per year. Our earlier projections were that we
would have to raise prices by $6 (to $34) but, for reasons 1 mentioned here two
months ago, we have been able to halve what we thought we were going to have to

THE ORIGINAL
Simply stated. Telewriter is the most powerful
word processor you can buy for the TRS-80
Color Computer. The original Telewriter has
received rave reviews in every major Color
Computer and TRS-80 magazine, as well as
enthusiastic praise from thousands of satisfied
owners. And rightly so.
The standard Color Computer display of 32
characters by 16 lines without lower case is
simply inadequate for serious word processing.
The checkerboard letters and tiny lines give you
no feel for how your writing looks or reads.
Telewriter gives the Color Computer a 51
column by 24 line screen display with true
lower case characters. So a Telewriter screen
looks like a printed page, with a good chunk of
text on screen at one time. In fact, more on
screen text than you'd get with Apple 11, Atari,
Tl, Vic or TRS-80 Model III.
On top of that, the sophisticated Telewriter
full-screen editor is so simple to use, it makes
writing fun. With single-letter mnemonic
commands, and menu-driven I/O and
formatting. Telewriter surpasses all others for
user friendliness and pure power.
Telewriter's chain printing feature means that
the size of your text is never limited by the
amount of memory you have, and Telewriter's
advanced cassette handler gives you a powerful
word processor without the major additional
cost of a disk.
...one of the best programs for the Color
Computer I have seen...
— Color Computer News, Jan. 1982
TELEWRITER-64
But now we've added more power to
Telewriter. Not just bells and whistles, but
major features that give you total control over
your writing. We call this new supercharged
version Telewriter-64. For two reasons.
64K COMPATIBLE
Telewriter-64 runs fully in any Color Computer
— 16K. 32K. or 64K, with or without Extended
Basic, with disk or cassette or both. It
automatically configures itself to take optimum
advantage of all available memory. That means
that when you upgrade your memory, the
Telewriter-64 text buffer grows accordingly. In
a 64K cassette based system, for example, you
get about 40K of memory to store text. So you
don't need disk or FLEX to put all your 64K
to work immediately.
64 COLUMNS (AND 85!)
Besides the original 51 column screen,
Telewriter-64 now gives you 2 additional high-
density displays: 64 x 24 and 85 x 24!! Both
high density modes provide all the standard
Telewriter editing capabilities, and you can
switch instantly to any of the 3 formats with a
single control key command.
The 51 x 24 display is clear and crisp on the
screen. The two high density modes are more
crowded and less easily readable, but they are
perfect for showing you the exact layout of
your printed page, ail on the screen at one
time. Compare this with cumbersome
"windows" that show you only fragments at a
lime and don't even allow editing.
RIGHT JUSTIFICATION &
HYPHENATION
One outstanding advantage of the full-width
screen display is that you can now set the
screen width to match the width of your
printed page, so that "what you see is what
you get." This makes exact alignment of
columns possible and it makes hyphenation
simple.
Since short lines are the reason for the large
spaces often found in standard right justified
text, and since hyphenation is the most
effective way to eliminate short lines,
Telewriter-64 can now promise you some of the
best looking right justification you can get on
the Color Computer.

I am pleased to report to you that RAINBOWfest in
Princeton was a success, as we expect February's show in
Irvine, Calif., to be. Now would be the time to order tickets.
It is over President's Day Weekend, so you'll have an extra
day to travel and to enjoy the fine weather in Southern
California. And. the holiday weekend means that Disney-
land will be open on Monday, as will all the other attractions
in the area. Plan to make a weekend out of it and come to the
"largest Color Computer Exhibition" ever offered, any-
where!
By way of finally, one of the things about which I have
become increasingly encouraged in the past few months is
the "language expansion" of CoCo.
Somehow, it has always seemed to me that havingjust one
language available for programming on any single computer
was a disadvantage — more perceived than real, perhaps.
But, it always appeared that the "big time"computers had a
wealth of language in which people could program.
Add CoCo to the list. LOGO has been available for some
time now; C is something that many programmers believe is
the "wave of the future"; pascal has a couple of versions
(and its own RAINBOW column); and now, CP/M is also
available from two manufacturers.
Which one is most significant? I don't know. CP/M gives
access to a wealth of programs that have been in use for
some time. PASCAL is very flexible, and very popular in
educational circles. C is, as I said, a "new" language that is
steadily increasing in popularity. And LOGO is an excellent
learning tool for youngsters.
Add those to BASIC and you can count five languages for
CoCo. Not bad. Not bad at all.

BUILDING DECEMBERS RAINBOW
The Adventure Contest Vote Is In . . .
The Chestnuts Are Roasting On The Fire . . .
And The Holiday Season Is Upon Us . . .
As this special Adventure issue of THE RAINBOW goes to press, our
peerless managing editor. Jim Reed, is off on adventures of his own in
Europe and Northern Africa. Jim. who usually "builds" THE RAIN-
BOW on this page each month, asked me to fill in for him in his absence and. I
have to admit. 1 was rather honored by the invitation. Jim is a lough act to
follow, but somebody has to do it.
We have a running joke around here about leaving pages empty and putting
"Notes" at the top. Besides, if somebody didn't build THE RAINBOW each
month. Roy G. Biv wouldn't exist, Judy Garland wouldn't have had anything
to sing about for all these years, and the Color Computer would have lost its
best friend.
Without question, the widest and brightest band in THE RAINBOW'S spec-
trum this month is. at long last, the announcement of the winners of the
Second Annual Rainbow Adventure Contest. I know that many of you have
awaited this moment with bated breath - or at least the contestants, anyway
and I'm confident that, after introducing yourselves to the two winners
published in this issue for a few hours, you will not be disappointed with the
wait. The Grand Prize winner, Steven Mitchell's Rescue On Alpha II. is a
graphics Adventure as good as any ever written in BASIC. And the 1 6K Best of
Show winner, Mark Nelson's Head Of The Beast, is a novel little Adventure
that works wonders within the limitations of the I6K environment.
With these two winners, you can be assured that multiple hours of enter-
tainment lay before you. And these are only two of the 18 winners selected in
the Adventure contest. The other 16 will lie dormant for a few more short
weeks until they burst forth in the second Rainbow Book Of Adventures.
When that time comes, you can don your vintage flight jacket, cock your
ledora down jauntily over your eyes, and say goodbye to your family for a
week or two — it's time for Adventure once again!
Going beyond Adventures, we mustn't get so carried away that we forget
that it's the holiday season. And not only is this the special Adventure edition
of THE RAINBOW, it's the special Christmas issue as well. Leading the holiday
parade of features this month is a program to set the tone for those that follow:
a music and graphics program that will do wonders for putting you in the
spirit ol the season. Following that is another graphics program, also sea-
sonal, that wishes your friends and family a holiday greeting that will warm
hearts in the coldest of weather.
But your CoCo shouldn't spend the entire holiday season playing carols and
making pretty pictures, should it? Let's put it to work so that you can do some
caroling of your own! Toward this end. we offer two programs that will make
the dreaded task of preparing holiday greeting cards as much a thing of the
past as adorning your tree with lighted candles. The first, a Christmas card file
and labeler, can be used to sort. list, label, delete, edit, update, and keep track
of incoming and outgoing cards — just about everything but lick the Christ-
mas seal! And then, a printer graphics program that will allow you to print
your own personalized greeting cards in five colors on an Epson or Gemini
dot-matrix printer.
So, as you can see, even though we've been up to our eyelids in Adventures,
we certainly haven't forgotten what time of year it is. And from the heart of
beautiful, downtown Prospect, all of us here at THE RAINBOW would like to
wish you the very happiest of holiday seasons. May the CoCo Community,
giving thanks for times past, turn now to a prosperous new year.

18 THE RAINBOW Dece
mber 1984
By Robert T. Rogers
This is a fun program for the holidays that combines
CoCo's great sound and graphics capabilities. It consists
of a series of Hi-Res Christmas scenes, each followed by
an appropriate holiday song. It should fit in 1 6K, even though it
was written on a 32K machine. If necessary, remove one picture
and its music. Unfortunately one cannot have graphics being
drawn or animation taking place during the PLA Ying of a song,
but it still is interesting. Anyone can add or change the scenes
and add new songs easily; just tack them at the end and change
the line with RUN in it.
Below is a listing of the scenes and songs:
1) Snowman, Frosty The Snowman (also circle designs)
2) Christmas Tree, Oh Christmas Tree
3) Star. Silent Night
4) Computer, Holly Jolly Christmas
5) House In Winter. White Christmas
6) Sing Along, Jingle Bells
7) World Flag Salute, Joy To The World
December 1984 THE RAINBOW 19
When typing the listing you
can omit the semicolons in the
PLA Kstatements. They were left
in the longer PLA Y statements
so that you can keep track of
your typing location. Also, many
of the LINE and CIRCLE state-
ments are on separate lines for
clarity; however they can be put
together on the same lines to save
memory/ time, just watch out for
a few GOSUBs. The different
segments of the programs most
usually end with PLA Y state-
ments and begin with PMODEs,
so if you need to eliminate rou-
tines to conserve memory, look
at these areas for hacking.
(Robert Rogers is a junior at Forest Hill
High School in West Palm Beach, Fla.,
who has been a self-taught programmer
for two years. His interests include per-
forming professionally on the organ
and model railroading.)

THE SPANISH ARMADA
In the summer of 1588 King Philip of Spain's
"Enterprize of England" sailed up the English
Channel while Europe watched in apprehensive
silence. The SPANISH ARMADA recreates the
problems faced by the English Commanders as
they struggled to defeat the Armada. Only this
time it's up to you! Using weapons of the day,
can you defeat the Armada? Cope with fickle
winds? A relentless current? Difficulty of supply?
It won't be easy, but it's fun to try.
The game requires at least a 32K computer
and is compatible with either cassette or disc
systems. Both versions are shipped on tape.

CONGRESS
An award winning political simula-
tion by Jeff Stevens. Have you
ever wondered what it feels like to
be the President of the United
States? Congress lets you be the
President. You select a program to
get through Congress. You decide
which states to influence through
pork-barrel legislation. You assign
lobbyists to the House or Senate,
and you determine how to use log
rolling favors. Finally, you decide
whether to sign a bill into law or
veto it. Your overall performance is
rated in comparison to the popular-
ity of other presidents. "Congress''
also serves as a fine tutorial on
how a bill becomes a law. It will add
a spark to any government class.
All would-be politicians will enjoy it

TURN OF THE SCREW
Have a CoCo controlled light
show with . . .
Lights!
Camera!
CoCo!
By Tony DiStefano
Rainbow Contributing Editor
This is an enlightening project
which involves lights. That's
right. acomputer controlled light
show. This could be used to light up
your Christmas tree, brighten up your
house or porch, or even change your
den into a disco. You know those strings
of lights you can buy at Christmas time
that come in sets of 20 or 30? They are
perfect to use.
Normally 1 would now start to des-
cribe how to put the project together,
get the parts and run the thing, but one
of my friends, Mike Schmidt, told me
that 1 would do well to explain the the-
ory of how my projects work. Well here
goes, a little explanation goes a long
way into understanding how the things
work.
The heart of the project is based on a
nifty little chip called a "thyristor." It is
better known as a triac. To fully under-
stand a triac, one must first look at an
SCR (Silicon-Cont rolled-Rectifier).
Figure I displays the schematic diagram
of an SCR.
There are three parts to an SCR. The
anode, the cathode and the gate. As you
can see by the diagram, it doesn't look
like more than a diode with another
wire going to it. Well, that's basically
what it is. The main part of it is a diode,
but this diode does not conduct in any
direction. It is an open circuit capable of
withstanding rated voltage until trig-
gered. That is where the gate comes in.
When a small current is applied to the
gate, the current path of the diode part
of the SRC becomes low-impedance in
one direction and remains so, even after
the trigger source current is removed. It
will remain so until current through the
path stops or is reduced below a min-
imum "holding'Mevel. An SCR is useful
for DC and half-wave AC applications.
Figure 2 shows the diagram of a
triac. It looks just like two SCR's back
to back. In fact, a triac is nothing more
than a bidirectional thyristor. A single
trigger source turns the device on for
load current in either direction. Since
FIGURE 1
GATE

I CATHODE
GATE

MT2l
they conduct in both directions, triacs
are useful in AC power applications
that require full source power control
capability to be applied to the load. This
capability is what we need in this pro-
ject. In short, a triac can be described as
an electronic switch. It can also be used
as a variable control switch, but that
capability will not be used in this project.
The Radio Shack Optocoupler is a
special type of triac device. Instead of
the normal gate controlled trigger, it has
an optoisolator device connected to the
gate. This is important to us because
high voltage like the AC coming from
the wall is very dangerous to a low vol-
tage computer. Even the slightest spike
of noise can destroy a computer. The
optoisolator part of this device will pro-
tect the high voltage from coming close
to your computer. Only one problem,
the current handling capabilities of this
device is too limited to be useful. So
we'll use it to trigger the gate of a more
powerful triac. The triac. in series with a
load (our lights) and the AC from the
wall, will complete a circuit. Before, I
told you that a triac is an electronic
switch. With the right signal to the
Optocoupler, we can control the load

an early specialist in computer
hardware projects. He lives in

(our lights) on and off.
We now know that the right signal to
the Optocoupler can turn our lights on
and off. What is the right signal? A
small current, say, from a computer, is
quite enough. The rest is quite simple.
One eight-bit latch to control the Opto-
coupler and eight resistors and we are
off. The rest is just construction. There
is a parts list in Table I .
All the parts that have a quantity of
"*" need explanation. You do not need
to make all eight of the triac circuit. It
all depends on your use. If all you want
is a light chaser, then you need only
three of each part. If you want to do
something more elaborate, you may
want to construct all eight of the triac
circuits. The maximum is. of course,
eight. More is possible but requires
more circuitry. I don't think there is the
need for more, but if there is, write to me
for details. As it is, the eight-bit latch is
memory-mapped at SFF40 (65433 in
decimal), so the use of this with a disk
drive is impossible unless you have one
of the expansion interfaces available on
the market.

This project is basically in two parts.
The first part is the computer side. The
only parts that go on the proto-board
(B2) are the latch, resistors and the
capacitor. What will leave this board is
a ground wire and one wire for every
triac circuit you need. You may connect
the two boards together directly or use a
connector. What connector you use
depends on how many wires you use.
Refer to the Radio Shack catalog for
the right connector.
The second part of the project is the
main board (Bl). It consists of all the
remaining parts. There is enough room
on the board to fit all eight triac circuits.
There is not much to this part, just
examine photo 1 for placement of all the
parts and follow the circuit.
Before trying this, you should run a
few tests. Plug in all the lCs except the
74LS374. Plug in the control box and
the lights. None of the lights should be
on. If some or all of the lights are on,
turn everything off and check your
work. Next, take a little piece of wire
and jumper pin 20 to pin 3, 4, 7, 8, II,
12, 15, 16 — one at a time. As you do

this each light should go on. If this is
OK. turn everything off and plug in the
last chip. To see if all is OK, turn every-
thing on. All the lights should be off.
Type POKE &HFF40.255, or POKE
65433.255. The 65433 (&HFF40 in Hex)
is the control byte. The lights should go
on. POKEinga zero into the same loca-
tion should turn the lights off. The short
listings provided will give you an exam-
ple of what you can do with the lights.
The last step is how to control each
light separately. POKEing a zero into
the control byte will turn off all the
lights. Each of the eight lights is con-
trolled by one bit. The first bit controls
the first light, the second bit controls the
second light, and so on.
Table 2 shows the decimal value of
each light. To have any light on, just
poke the decimal value of the light
number into the control byte. If you
want more than one light on. you must
add the decimal values of each light.
Example, if you want light 2 and light 6
on, you must do 2 + 32 = 34. POKE 34
into the control byte. 1 wrote a little
program in basic to give you an exam-
ple of what you can do with these lights.

There are a few things to remember,
though. Each individual triac circuit
load (light or set of lights) must not
exceed 400 watts and the total power
must not exceed 1200 watts. To get the
chaser effect, you need just three triac
circuits and three sets of lights. Arrange
the lights in parallel and tie them to-
gether so that the sequence of lights goes
1,2, 3 ... 1, 2. 3 .. . 1.2.3. RUN ihe
chaser program and. there you have it.
It has been brought to my attention
that there seems to be a problem with
my parallel printer adapter. The prob-
lem is with the grounding of pin 18.
While on my Epson printer. 1 have no
problems, on most printers there is a
positive voltage on this pin. Connecting
this in to ground can cause damage to
the printer. To solve this do not ground
pin 18 in the output connector. "^

New Revisions In CoCo's
ROM
By Andv Kluck
30
THE RAINBOW
December 1984
In response to a lack of information
from Radio Shack on the newest
revisions of the CoCo's ROMs and
the bugs in the old ROMs they replace. I
have compiled this article to explain the
major differences between them. Also
included is a utility program for use in
64K systems for installing any set of
basics in RAM from files. Numbers in
parentheses are approximate addresses
of some of the ROM changes.
Color basic 1.1
The most important difference
between Color basic 1 .0 and 1 . 1 is that
the Reset routine (SA027-SA06D or
-SA073 in 1 . 1 ) of I . I has the added abil-
ity to detect the 64K RAM jumper and
properly initialize the SAM to use 64K
RAMs. In order to make room for the
extra code required to make this test,
the initialization routines (SA06E, or
SA074 in I.I through SAOCA) have
been largely rewritten. The keyboard
scan routine (SAICI-SA26D) has also
been rewritten to prevent the joystick
buttons from causing a string of false
characters to be detected. The printer
driver (SA2C5-SA2FA) has been modi-
fied to send eight bits per character
(Andy Kluck is an electrical engineering
student at the University of Texas at
Austin.)
instead of seven. A bug($A440) in the
CLOSE routine for output files that
prevents writing of the end of file mark
for files with lengths that are integer
multiples of 255 has been fixed. Because
of this problem, reading such a sequen-
tial file (of length 0. 255. 510, etc. bytes)
written by Color basic 1.0 causes the
computer to keep searching for the next
record past the end of the file. However,
Extended BASIC 1 .0 and 1 . 1 both fix this
bug using a RAM hook, so only BASIC
1 .0 without Extended BASIC causes this
problem. Finally, an error (SA6EB) has
been fixed to allow for visible blinking
of the corner of the screen during
SKIPFing of ungapped files, such as
those made by CSA F£and CSA VEM.
The major incompatibility problem
caused by these changes is that the few
programs using the keyboard scan rou-
tine to detect the joystick buttons may
now require certain keys on the key-
board to be used instead.
Color Basic 1.2
The major change made in the 1.2
BASIC ROM is that the routine that tests
for the BREAK and Shift @ keys before
each BASIC statement ($ A 1 C I -A26D) is
executed now scans the keyboard only if
at least one key is held down. This
results in faster execution of BASIC pro-
grams whenever no keys orjoystick but-

range from a few percent in programs
with lots of slow instructions to 200 per-
cent in programs like:

In order to implement this, the key-
board scanner has been compressed,

''The most important

BASIC 1.0 and 1.1 is that

at SA000. In revision 1.2. SAICI is the
address of the routine which quickly
tests the keyboard and then scans the
keyboard normally only if at least one
key is held down or otherwise clears the
A register and returns. Therefore, ma-
chine language programs that call SA I C I
to scan the keyboard may work nor-
mally except that they do not accept any
keyboard character twice in a row.
because the rollover table is not updated
between key presses. For the same rea-
son, BASIC programs, which test the
keyboard rollover table at SI 52- 1 59 to
detect which keys are pressed (a tech-
nique which has been referred to as
"'auto repeat"), may receive a false indi-
cation that a key is being held down
after it has been released, until another
key or joystick button is pressed. For
example, this routine tests if the 'Q' key
when held down keeps printing the mes-
sage after the 'Q' is released until another
key is pressed in Color BASIC 1.2:
10 IF (PEEK(&HI53) AND4)=0
THEN ?"Q DOWN"ELSE CLS
20 GOTO 10
which has the effect of speeding up exe-
cution in the same way as Color BASIC
1.2, so that a system with either one or
both of new ROMs will run at the
increased speed. GET. PUT. and LOC
have been modified to work with record
numbers up to 65535 instead of just
32767. Extra error checking has been
implemented in some places, and most
of the bugs in the close routine for ran-
dom files have been fixed. Closing ran-
dom files in any order other than last-
opened, first-closed caused a system
crash in Disk BASIC I.I, and this has
been fixed (SCB93-SCBBI in new
ROM): however, a similar crash in the
close routine after an I/O Error while
the file is open during COPY has not.
This last problem will probably require
major patches in COPY. CLOSE, or
both to fix. In Disk BASIC I.I. closing a
random file no longer (SCACB in old.
SCB80 in new) deletes strings fielded in
buffers other than the one being closed.
vector at $ A000 has moved from SAICI
to SA1CB. There are also some minor
changes. The 1 .2 printer output routine
(SA2C3-SA2FA) waits for a ready sig-
nal from the printer before and after
sending each character instead of only
making this test after sending like the
earlier ROMs. This prevents the loss of
one character that may otherwise have
been outputted before the printer was
ready. Also, the initial Baud rate con-
stant (SA I 14) has been changed from 87
to 88. apparently in an attempt to more
closely approximate the correct Baud
rate.
A new patch (SB23F) prevents a syn-
tax error when a Hex or Octal constant
is preceded by a plus sign with Extended
BASIC installed PRINT + &H20 incor-
rectly gives an error in the "get operand"
routine has been patched (SB3ED-
SB426) to give a TM Error when a string
is used as the argument for some func-
tions that should require numeric
arguments. For example, CLEAR:
PRINT EOF(A$).CHR$(A$) gives no
error in Color basic 1 .0 and I.I. Finally,
the floating point bug($B9D6) has been
fixed so that CoCo no longer thinks that
PRINT 1000 + I E-38 'Correct answer is
WOO is 1 E-38. Watch out for programs
that call the keyboard scanner directly
at S A I C I instead of through the vector
Extended Basic 1.1
The most important change in
Extended BASIC LI is that PC LEAR
has been patched (S96A3-S96B3.
S80D0-S80DD) to work properly inside
a program. Also, PRINT USING has
been patched (S9I79. S9I7D) so that
numbers printed in exponential format
with exponents greater than nine are
not botched up as in Extended BASIC
1.0. Another patch (S8C1B-S8C22,
S8C5I) fixes DLOADM; under
Extended BASIC 1.0 without Disk
basic, it didn't work at all.
Finally, />A/OZ)E($962C-$962D) now
tests location SBC to find the correct
start of graphics page one instead of
assuming it is $600: this was not a major
problem, since $600 is always the start
of page one except with Disk BASIC,
which fixes PMODE by itself through a
RAM hook. The most likely problem
caused by the changes is with programs
that use a PC LEA R routine that calls
the ROM's PCLEAR routine in the
area $96A5-$96B3. which has been re-
written; such routines need to be replaced
with an equivalent designed to work
with either ROM.
Disk Basic 1.1
First of all, Disk BASIC I . I adds a new
interpret loop ($C8B0-$C90B in new
ROM) through one of the RAM hooks.
"There is an error in
the Disk 1.0 DSKINI
routine . . . [which] is
fixed by an instruction at
$D5F1-$D5F2 in the new
ROM...
Also, in the old ROM, string array ele-
ments fielded in an7 random buffer
while any random file is being closed
may have their descriptor addresses
messed up. causing general confusion,
and this has been fixed (SCA8C-
$CAD5 in old. SCB3D-SCB88 in new)
in revision LI. The bug in FILES that
was analogous to the PC LEA R bug has
been fixed (new code at SD1E2-
$DI EE). along with the one (new code
at SD1A8-SDIAE) that sometimes
causes FI LES to allocate the beginning
of graphics area to an odd page where
the SAM could not display it. Also, in
Disk BASIC 1.0 the FILES statement
reserved one more byte for random file
buffers than was requested: FILES

THE RAINBOW

2.200 would allow a random file to be
opened with a record length of 201; this
is corrected (instruction at SD0AB-
SDOAC in old ROM removed) in revi-
sion 1.1. A bug that could bite (byte?)
multi-drive systems causing wrecked
file allocation tables after files are writ-
ten on one drive while files are opened
on the next higher drive (wrong index in
instruction at $C70C-$C70D in old
ROM) has been fixed. Also, in Disk
BASIC 1.1, the prompting string in the
statement INPUT #DN."INPUT
NUMBER "; N$ is ignored (by new code
SC860-SC887) unless DN isO, in which
case it is printed to the screen. The old
Disk BASIC would have printed
"INPUT NUMBER" into the random
file buffer, if DN were an open random
file. A new command, DOS (main rou-
tine , SDF00-SDF4B) has been added,
which loads all of track $22 (34) from
drive starting at address $2600 and
jumps to $2602 if the characters in
$2600-2601 are "OS." DOS appears to
have been implemented by Radio Shack
instead of Microsoft, and is not well-
written; depending on various circum-
stances, DOS may erase part of the
! BASIC program, variables, stack (caus-
ing a crash), or strings before testing for
"OS" to see if the disk is even bootable.
For what it's worth, DOS may be
called from machine language by JMP
[$C00A] using a vector new to Disk
BASIC 1.1. There is also a new vector at
$C008, called during initialization,
which points to a routine ($DF4C-
$DF58) that sets the RAM vectors for
SWI2 and SW13 to RTIs; for some
unknown reason a SWI3 is used at the
beginning of the DOS routine. The
SWI2 and SW13 to RTIs; for some
unknown reason a SWI3 is used at the
beginning of the DOS routine. The
(warned users to press Reset after each
DSKINl command when doing more
than one disk at a time to ensure proper
formatting. There is an error in the Disk
1.0 DSKINl routine which causes the
write-precompensation flag of the disk
controller, which is supposed to be set
only for track numbers greater than 2 1 ,
to be set while formatting all tracks if
DSKCON's track register is set greater
than 2 1 when DSKINl is executed, pos-
sibly causing I/O Errors. This which is
fixed (by an instruction at $D5FI-
thenew ROM, and it appears to be what
Radio Shack was referring to, although
the description doesn't exactly match
the problem. The error does not only
occur when DSKINl is used more than
once; it can happen any time when the
last sector read was on a track greater
than 21; and besides, pressing Reset
doesn't prevent the problem, because it
doesn't change the track register. How-
ever, doing a DIR of any drive, or a
POKE &HEC.0 before each DSKINl,
will. There are also changes in other
parts of the ROM that I wasn't able to
analyze which may suggest other prob-
lems in the old ROM. Because the
ROM has been completely reas-
sembled, all useful routines have been
moved, including DSKCON. There-
fore, most programs that call any Disk
ROM routines except DSKCON
through the vector at $C004 won't work
with Disk BASIC 1.1. This does not
necessarily mean that such programs
are obsolete with the new ROM if they
will run in the 64K RAM mode, since
"The most annoying
problem that should have
been fixed but wasn't, is
Disk BASIC'S lack of a
suitable method of
synchronizing the disk
head of each drive when
it is first used."
this allows the user to install the old
Disk BASIC in RAM.
What They Didn't Fix
The most annoying problem that
should have been fixed but wasn't, is
Disk Basic's lack of a suitable method
of synchronizing the disk head of each
drive when it is first used. The current
software just assumes that each one is at
track zero, and if this isn't correct,
DSKCON attempts to read the wrong
track before finding the correct posi-
tion. If the head position is initially
inside of track 1 7, it results in ramming
the mechanism against the inside stops,
often knocking the drive so far out of
alignment that the head must be syn-
chronized to track zero two times before
it finds the directory. The right way
would be to initially set the track coun-
ter of each drive to some out of range
value, and have DSKCON upon finding
this value either synchronize the drive to

The Biggest
The Best
The Indispensable
It's called the premier Color Computer magazine lor good
reason The Rainbow is, the biggest, best, brightest and most
comprehensive publication a happy CoCo ever had! Is there any
wonder we get letters daily which praise the Rainbow, the maga-
zine one reader calls "A Pot Of Gold" lor his Color Computer?
The Rainbow features more programs, more information and
more in-depth treatment of the TRS-80 Color, TDP System-100,
MC-10 and Dragon-32 and 64 computers than anyone else.
Each monthly issue has as many as 340 pages and contains as
many as two dozen programs some 15 regular columns and 30 or
more product reviews. And advertisments; the Rainbow is
known as the medium for advertisers — which means every
month it has a wealth of information unavailable anywhere else
about new products 1 More than 200 companies advertise in its
pages every month
But what makes the Rainbow is its people. People like Bob
Albrecht. the master teacher of computer programming. People
like Don Inman. one of the world's best computer graphics
authors. Experts like Dick White, one of the most knowledgeable
writers about basic. Or, Dan Downard, Rainbow technical editor,
who answers our readers' toughest questions. Educators like
award-winning Rainbow columnist Steve Blyn Advanced pro-
grammers like Dale Puckett. who guides you through Radio
Shack's OS-9 operating system Electronics specialists like
Tony DiStefano, who explains the "insides" of the CoCo. These
people, and many others, visit you monthly through columns
available only in the Rainbow.
Innovative ideas, like our Scratch and Sniff Adventure or our
Anniversary special "soundsheets" with recorded programs, are
ready to feed right into your computer! Complete Adventure
games and Simulations. The Rainbow's unique Scoreboard of
arcade games And games — lots of them — super graphics and
utilities, the world's first four-color computer magazine center-
fold 1 And much, much more.

track zero, or even better, attempt to
read an address field and use its track
number.
The program listed below can be used
to load any available combination of
the three BASICS into RAM, either to
substitute Disk basic 1.0 for a newer
version ROM to run an incompatible
program, or to upgrade to the revised
versions. It requires 64K of RAM, and
copies of whichever basics are to be
replaced. To make these, you need to
temporarily acquire a CoCo with the
ROM versions you need, and make the
necessary files,
(C)SAVEM "CBASIC12".&HA000,
&HBFFF.&HB44A
(C)SAVEM "XBASlCir,&H8000,
&H9FFF.&HB44A
(C)SAVEM "DBAS1CI l",&HC000.
&HDFFF.&HB44A
changing the filenames according to
which version you're getting; i.e.,
"DBASICIO" for Disk 1.0 ROM, etc.
To determine the revision numbers of
the Color basic and Extended ROMs
in each system, these statements may be
used:
PRINT PEEK(4l301)-48 ' Revision
of Color basic
PRINT PEEK(33023)-48 ' Revision
of Extended basic, if applicable.
Of course, if you don't feel like pirat-
ing the basics you need, you can always
ask Radio Shack for help in getting
your ROMs replaced. To use the
INSTALL program, place either the
word "INTERNAL"ora filename to be
loaded for one of the three basics in
each of the DATA statements in Lines
280-300, in the order of Color BASIC,
Extended basic. Disk BASIC. If all three
are "INTERNAL," INSTALL simply
copies the basics unchanged from
ROM to RAM. To make the cassette
version, change the LOADM in Line
130 to C LOADM, and remove Line
170; also make DATA statement in
Line 300 "INTERNAL" unless you
want to add Disk BASIC. Either save the
program on a disk with copies of the
ROM files, or on tape, preferably fol-
lowed by the ROM files, and run it.
INSTALL operates in two different
modes depending on whether Disk
BASIC is loaded or not.
If Disk Basic is not loaded, no
adjustments are necessary to BASIC'S
internal variables; in this case the user
may insert a line like: 70 RUN "PRO-
GRAM" to RUN an application pro-
gram after loading the set of BASICS.
Afterwards the user may POKE
&HFFDE.0 or press Reset to switch
back to ROM BASIC, and then POKE
&HFFDF.0 to bring back the RAM
version.
If Disk BASIC is loaded, INSTALL
assumes it is of a different revision than
the one in ROM. Because different revi-
sions of Disk BASIC have their routines
moved around, it is necessary to set the
hooks and other variables according to
the new BASIC. This is done by calling
the Extended basic cold start routine at
$8002, and results in an automatic
NEW and printing of the sign-on mes-
sage. The practice of using POKEs to
switch between RAM and ROM causes
a crash if a different version of Disk
BASIC is in RAM because of incompati-
ble hook addresses. Reset may be used
to bring back the ROMs, at least with
Disk BASIC 1.0 and 1.1, but BASIC will
be cold started because the Reset vector
at $71 no longer points to a NOP
instruction.

This is the second of a three-part series on diskette file organization
The Diskette
Directories
Handler System
Part 2
By Marvin E. Swan
Last month program DIRI and
reports one through lour were
presented. This month. Part 2.
with program DIR2 and report 5 is
being presented. You must run last
month's program before running this
month's program. Next month. Part 3,
with final program DIR3 and reports 6.
7, and also program DIRO which gener-
ates a quick and dirty documentation
report will be presented.
Refer to last month's article for a
complete overview of all seven compre-
hensive reports generated by the Handler
system and an explanation of last
month's program DIM. To refresh your
memory, here is the cross relercnce ol
all programs and reports and their RUN

THE RAINBOW 37
Diskette Gum Labels Report 5
This month, report 5 is generated by
program DIR2. The purpose of report 5
is to print diskette names onto gum la-
bels for attachment to your diskettes.
Two sizes are available: 3 l A x 'Vie inches
and 4 x I ''/in inches.
Program DIR2
The purpose of DIR2 is to print
diskette names onto diskette gum la-
bels. A choice of two label sizes is avail-
able. DIR2 prompts you to place the
proper sized labels in your printer then
gives you a printer line-up procedure.
DIR2 is automatically run by program
D/RI if you previously selected report
option 5 during DIRI processing, oth-
erwise. DIR2 is bypassed and program
DIR3 is automatically run. When DIR2
is complete, it automatically runs DIR3.
The following BASIC line numbers con-
tain Epson brand printercodes that you
may change to satisfy your printer re-
quirements: 0510. 0960. 1020. 1030.
1040 and 1330.
A Continuing Saga . . .
Next month the final program DJR3
will be presented, which generates Con-
solidated Directories report 6 (the most
important and useful of all seven re-
ports) and Disks Directory Summary
report 7. Also, program DlRO which
prints a quick and dirty explanation of
the Handler system when you can't find
your RAINBOW for reference (shame on
you). So long until next month.

by
CHERRYSoft
Learning to type the right way can save you hours of
tedious work when entering programs Into your CoCo, and
this Is just what ETT was designed to do. Devote a little time
every day practicing with ETT and before you know It you will
be typing with confidence. Entering those programs will no
longer be the chore It used to be.
ETT's video keyboard lets you practice with all the keys
labeled, all the keys blank or only the "home" keys labeled.
The visual cues guide you while you learn to type without
watching your fingers. ETT shows your accuracy, response
time, and words per minute. You will quickly see that you are
Improving with practice.
With the sentences provided by ETT learning to type can
be fun. Over 1000 variations chosen because they include
every letter in the alphabet. You can also create your own
practice sets. This outstanding program was written by a cer-
tified teacher and professional programmer and comes with
a ten page student manual-study guide. Requires 16K Ex-
tended Basic.

Aside from carrying out the gar-
bage, income taxes, and trying
to get the kids to bed, one of the
tasks 1 dread most is sending out the
Christmas cards. When we purchased
our first Color Computer, 1 thought the
latter was the ideal application for the
common good of the household. It was,
and the original program has served us
well for the past three years.
(James D. Ball holds degrees in business
and chemical engineering. He is man-
ager of new technology and market
research for the Norton Company.
Chemical Process Products Division
located in Akron, Ohio. He is a self-
taught programmer and married with
two children.)
42 THE RAINBOW December 1984
That original program had everything
desired; all the necessary functions, ease
of use, idiot-proof features, and a for-
mat that was very workable. It also had
its limitations. The big limitation was
that it was based entirely upon I/O to
the disk for all operations. That's okay
provided the system isn't in its seem-
ingly cyclic directory crash mode. Too,
because it was all 1/ O disk-based, it was
relatively slow.
Due to the fear of directory crashes
and inherent slowness, 1 decided to re-
write the program. I wanted to retain
the original features but convert the
program to all in-memory operation.
This would be fast yet sufficient for a
mailing list/ record base which was not
meant for extensive records.
The rewrite proved to be no small
task but armed with the Colorkit (avail-
able through Prickly-Pear Software),
the task was somewhat simpler. Like
others, 1 find it difficult to suppress the
urge to expand upon an original work.
This was no exception. The labeler sec-
tion to the rewrite is an example of
incorporating several tricks learned over
the years. Ultimately, added features
had to be excluded due to memory
limitations.
About The Program
The program is usable from the start
with nothing special to learn, no
preloading of screen utilities, no machine
code to understand, no preliminary
PEEKs or POKEs, and no alternative
operating system. The minimum require-
ments include a 32K. Color Computer
operating under the "standard" Disk
BASIC and drive 0. A printer is obviously
necessary for hard copy. The program
functions include: sorting, listing, label-
ing, editing, deleting, updates, and track-
ing incoming and out-going cards by
year.
Since the program is used seasonally,
error trapping is extensive lest we forget
procedures. Everything is menu-driven
and the option to escape to the main
menu is strategically present along with
all request prompts. As presented, 100
records can be read into memory. This
is more than enough for most uses.
Should the cost of postage ever decline.
or the number of acquaintances increase,
up to 125 records can be accommo-
dated. Make a second file (on another
disk) or wait until Tandy decides to
issue a new ROM which would move
the resident code further up in memory.
To eliminate extensive disk I/O, the
entire file is read into a single-dimen-
sioned string array upon initialization.
All maintenance, input and output is
accomplished from memory. Only if the
file option is selected will the disk be
accessed a second time to document the
changes.
Lists are available to the screen or
printer. The lists available include cards
sent or received in a selected year, or the
entire file in increment pages for the
screen option. For the labeler, output
options include individual labels, a full
run, or a run by target/ non-target ZIP
code. A tab spacing test is available and
labels may be printed in single- or
double-column format. With the excep-
tion of individual labels, output is keyed
to the current year requested at the start
of the run.
When the program is loaded, the
cover screen and credits are displayed
with a request to insert the data diskette.
(I've grown fond of separate data files.)
Initialization is immediate upon answer-
ing the request and takes you into the
main menu. If no records are resident
the only options accessible will be data
entry (option 4), or exiting the program.
In the data entry mode, a request is
made for the current year. Next are the
December 1984 THE RAINBOW 43
name and address entries. A fore-title
selection (Mr. and Mrs., etc.) is pre-
sented along with the optional "& Fam-
ily." Next is the last card received (two-
digit year) and a "Send card this year
(Y/N)?" which relates to the current
year input earlier. In all, nine string
fields are recorded per a 75-character
record. Each entry is error-trapped and
space padded as necessary.
After all data has been entered into
memory, a sort (option 5), may be per-
formed if desired. Prior to hard copy
operations a sort will be required if

there are deleted records present, but
the program will inform you of this.
Any option can be invoked at any time.
When finished you can exit the program
(option 7), but if not, you can file
(option 6) the memory contents for the
next time. In fact, it's good procedure to
invoke the file option before utilizing
the labeler.
The next time the file is accessed,
you'll probably wish to update the cards
received through option I. This same
option can be used to edit the entire
record or to delete it. These functions
are performed sequentially or selectively
through checking names. You only need
to input the first few letters of the target
name to be presented with records from
which to choose. If you're unsure of the
spelling, you can check the full listing
(option 2) in the screen mode.
Program Techniques
For those interested, you'll notice
I've chosen to utilize direct access
files because it is simpler and allows
greater versatility. Sequential files could
have been used as well with some altera-
tions to the initialization and filing
sequence. Such alterations could also
apply to tape files but Extended Color
"The program functions
include: sorting, listing,
labeling, editing, deleting,
updates, and tracking in-
coming and out-going
cards by year.
BASK" is mandatory. Any such file alter-
ations I leave in your hands.
Each field is concatenated in order
and placed into a string array A$().
Field changes utilize the MID$ function
extensively. This is efficient and saves
on garbage collection (not the urban
type). The variables I and R designate
the current array (record) number, de-
pending upon the operation. Periodic
checking is done to verify the last record
on file, Z. The maximum allowable
records, XF, is initialized to 100 and is
independent of the file to be used mean-
ing the original file can be extended if
XF is achieved in earlier sessions. There-
in lies a major difference between direct
and sequential files in this application.

Initialization accounts for all records
plus the available space between Z and
XF which is set to null strings. Sorting
climinatesalldeleted recordsand alpha-
betizes the array. This sort is done on
the first field. NAMS. A deleted record
is recognized by substituting the first
string character with CHR$(128) which
places the string at a higher value than
lowercase "z"and can subsequently be
eliminated. The major variables are
listed in Table 3.
At the start of the program a PC LEA R
1 is performed to allocate memory as
long as this program — over 14800
bytes. The choice of PC LEAR 1 as
opposed to a PC LEAR is based on
ease of use. No need to preset parame-
ters. Enough string space is cleared in
Line 230 for 100 records. To increase
this to 125, set XF accordinglv and
CLEAR 10000.
I'm certain we all have our idiosyn-
crasies in programming. One of mine is
to exit the program from one and only
one location, the main menu. This is
beneficial though, as this program in-
corporates the high speed poke. These
pokes, in strategic locations, can be
eliminated should your machine not be
able to endure the hardship. Too. Epson
printer control codes are employed but
these can be easily changed or elimi-
nated to suit your needs. The program
defaults the printer Baud rate to 9600.
This can also be easily changed. I would
suggest though that you experiment
with the Baud rate poke in Line 1950.
My experience is that it is not always as
presented in the computer manual. Table
2 gives the locations of the potential
alterations.
In Summary
This rewrite of the original program
has met virtually all my criteria,
however, it is long and possibly difficult
to enter. As BASIC skips around a bit,
I've tried to maintain some semblance
of control in order to follow the logic. It
could be worse. Because of memory
constraints coupled with my wordy
programming, you'll note the lack of
space delimiters. I offer no other excuses
but if you get this up and running, you'll
lhank me. If you study the program you
will most likely get some ideas. It has
served as a base for other programs I've
concocted with yet different filing
schemes.
Asa side note, Tandy has a wonderful
machine in the CoCo. I think enough of
it that I'm on my second. The first was
donated to our local school system.
They're happy, Tandy is happy, and my
accountant is happy.

Season's
Greetings
By Joseph Kohn
This program can be either an ideal elec-
tronic greeting card for your CoCo friends
or a conversation piece for display on the
TV during holiday get-togethers. Utilizing
PMODE 3 graphics, a four-color animated
greeting is conveyed for Christmas and
Hanukkah.
The animation consists of blinking lights
on a Christmas tree and flickering candles
on a Hanukkah menorah. A random
selection of PSET instructions for the
lights and DRA W instructions for the
flames achieves the desired effect.
There are two provisions for per-
sonalizing the greeting. Line 40
allows any desired message to be

ADVENTURE CONTEST
Presenting the winners of the Second Annual
Rainbow Adventure Contest . . .
Computer Adventure games: There are those of us
who believe that no other type of game ever created
can compare favorably. They really are remarkable.
Like a lot of other people. I have been hooked since the first
time I punched GO NORTH into a Color Computer key-
board. For this reason above others. 1 was quite pleased to
be invited to coordinate the judging of the Second Annual
RAINBOW Adventure Contest.
Since then, the word "overwhelmed" has taken on a whole
new meaning for me.
Nearly 150 programs were received as entries into this
year's contest from nearly every state in the union and from
several countries around the globe. This is surely one of the
largest -- perhaps the largest - collections of computer
Adventure games ever assembled. In any language. For any
machine. On any planet.
Now try to imagine, if you will, making it through that
many Adventures with an eye towards the best. Nearly 150
programs, and almost every one of them packing 32K of
RAM up to the CoCo's heat vents! Can the magnitude be
translated'.' 1 mean, this is not like tasting wine or watching a
swim suit competition. These things take days to solve and
evaluate!
But the judges have persevered (although we lapse now
and then into verb/ noun speech), and we are now able to
announce the winners of the contest: those 18 Adventures
that were judged to be the best conceived and best con-
structed of all the entries. Not only do these programmers
deserve the prizes that they have received, but they also
deserve a tremendous amount of recognition for the hard
work, knowledge and skill that they have applied toward
their creations.
There may be some debate in Adventure circles as to
whether graphics programs are truly better than the all-text
games. Many people prefer books over film and television
because books allow the imagination to play a more active
role in the experience. But the debate can go on beyond this
year's contest; here, at least, it is the graphics entries that
most impressed the judges. Although there are enough 200-
room games among the winners to appease even the most
diehard all-text Adventurer, the graphics literally stole the
show.
Also of note this year is the number of winners that fall
64 THE RAINBOW December 1984
By Kevin Nickols
into the "Dungeons & Dragons" variety of games. These
games, although not true Adventures in the strictest sense of
the term, are still comprised of many of the classic Adven-
ture elements. The lines between these and arcade-type
games are becoming less and less distinct. Besides, they're
great games and they deserve recognition somewhere, don't
they?
I believe 1 can forego going into just how extraordinarily
sophisticated many of the entries were this year. With two of
the winners published in this issue of THE RAINBOW, they
can speak far better for themselves. And as you're playing
the Grand Prize winner, bear in mind that — as excellent as
it is — it is not a stand-out program, towering above the rest.
It was able, however, to maintain the edge on a fantastic
field of finalists. Until the rest of these finalists are published
in the second Rainbow Book of Adventures, we hope these
two current offerings will help to quench that burning thirst
that drives man ever in search of Adventure.
With this, we take great pleasure in presenting the follow-
ing awards to the 18 finalists in the Second Annual Rainbow
Adventure Contest:
The Law Enforcement Citation is awarded to Jeff Crow,
of Canyon Country, Calif., for his entry, Chief Inspector. If
you can solve this one very quickly, you should be working
for the police. A whodunit in the grandest style. Chief
Inspector has you reading statements, collecting evidence
and filling out accusation forms in an attempt to solve the
murder of a wealthy business executive. But you won't find
any magic spells in this Adventure; only logic and deductive
reasoning can see you through to the solution.
The John Lennon Memorial Award is given to Mark
Fetherston, of Kenosha, Wis., for Yellow Submarine. An
attempt to base an Adventure on this Beatles' classic was an
ambitious undertaking that Mark has managed with remark-
able success. His story line remains true to the original, his
numerous graphics screens appear to have come straight
from the original movie and, further, he manages to preserve
that feeling that John and the Beatles were able to arouse in
many of us during those days. After all. love really is all you
need.
The Best Packaging Citation is awarded to J.C. Jackson
of Owings Mills, Md., for his entry, Stowaway. This pro-
gram was submitted packaged better than a great many of
the programs being sold on the market. But the packaging
does not tell the whole story; it merely augments a smooth-
running program with what is probably the most surprising
ending of any entry in this year's contest. Furthermore, it
makes extremely good use of several graphics screens, prov-
ing that graphics need not be elaborate to be effective.
The Equal Opportunity With CoCo Award goes to Jane
Fisher of Raleigh, N.C., for her entry. The Caves OfKalakh.
We were pleased that we had so many female contestants
this year and we're even more pleased that we are able to list
one of them among the winners. What is more. Jane's entry
was the only one written entirely in assembly language.
Believe me, the speed with which the program reacts to
commands was greeted cheerfully by the judges.
The Key To The City Award goes to a local entrant, T.
Robert Poppe of Louisville, Ky., for The Riddle Of Ran-
domar. Robert says that the Adventure is for beginners since
he is a beginner himself, but he is being far too modest. This
enjoyable program fared well among some very stiff compe-
tition and the graphics screens can hold their own against
any competitor.
The G-Man Medal Of Honor is awarded to David Daw-
son of Omaha, Neb., for his Adventure entry. Agent. David
uses some interesting line graphics to set the scene for this
espionage thriller that requires you to identify your quarry
and your contacts by their facial features, obviously some-
thing that demands clean and precise graphics.
The Most Unusual Of Show Award goes to Larry Lans-
berry of Phoenix, Ariz., for The Wands OfRaga-Dune. This
program is so different that it defies categorization, incorpo-
rating elements of all of the other categories. The game takes
place in an area of 1,230 rooms, surrounded by a desert
limited in size only by the computer's ability to keep adding
by one, yet it still maintains logical entry points to each of
the screens. This one really has to be played to be understood.
The Bronzed Titanic Life Preserver Award goes to Scott
Settembre of Monroe, N.Y., for Lost Island. Another great
graphics Adventure, this program interweaves the graphics
very effectively into action. Scott has created an Adventure
in the finest form.
The Space Cadets Merit Badge is awarded to Steve
Skrzyniarz of Tacoma, Wash., for his non-graphics Adven-
ture entry, Lunar Escape. This prpgram leads you through
137 rooms, mostly on the lunar surface. That means that you
have to be very, very careful throughout.
The Neatest Trick Award goes to Robert W. Mangum of
Titusville, Fla., for The Hero Of Lonesome Valley. Besides
being a smooth-running and well-conceived Adventure, this
program has an interesting surprise in the listing that was
worth a couple of double-takes and an honorable mention.
Dungeons & Dragons Second Runner-Up is Darin An-
dersen of Smithfield, Utah, for Dark Castle. Darin's game
uses cursor key control to guide the figure through monster
after monster after monster. The only break from the action
is when you are able to return to the store for more healing
potions, weapons, armor and all the other elements inherent
in this type of game.
Dungeons & Dragons First Runner-Up is L. Curtis Boyle,
of Saskatoon, Saskatchewan, for his entry. RingQuest.
Although this program more closely resembles the standard
Adventure format than some of the others, it incorporates
the hit points, healing potions, etc., that tilt it into the D&D
category. The information is presented on the screen in a
very nice manner, including graphics of the monsters
encountered and the objects in view. In whatever category,
this program is a winner.
Non-Graphics First Runner-Up goes to Glen and Bret
Dahlgren, of Pittsburgh, Pa., for their entry. Castle Of The
Creator. With an inverse red display showing all possible
information, this program should prove to be enough to
keep the most experienced Adventurer busy for days or
weeks. And since this game is only the first part of a pro-
posed trilogy, the following chapters may very well turn into
a lifetime project.
16K Best Of Show is awarded to Mark Nelson of Orem,
Utah, for his entry. The Head Of The Beast. This interesting
game, which appears in this issue, takes the novel approach
of using a joystick to select all commands. It plays smoothly
and has a range that is difficult to achieve within the confines
of a I6K. system. Mark has been able to overcome the
limitations and produce a winning Adventure.

wizards, is masterminding this new
threat to the security and peace of the
galaxy. And if memory serves, those
wizards were a particularly nasty bunch.
Their sect was wiped out by a govern-
ment attack on their home planet dur-
ing the last consolidation wars, and the
few wizards who happened to be off-
planet at the time have been vowing
revenge ever since.
The story is that several months ago,
a scientist doing research in controlled
animal mutations. Professor Ion Smart-
guy, disappeared without a trace from
his laboratory on Outpost VI. Not much
importance was placed on the matter at
the time; after all, it's a big universe, and
people disappear all the time for one
reason or another. But the intelligence
division of GSS has now learned that
Professor Smartguy was kidnapped by
Zarkon and is being held in a research
bunker on a small planetoid known as
Alpha II. According to the intelligence
reports, Smartguy is being forced to
breed an army of mutated, killer beasts
— a destructive force more powerful
than any before it — which Zarkon
intends to unleash upon the galaxy.
In fact, if the reports can be taken
seriously, he has already assembled a
sizable force of these giant mutants
which he uses to augment the legion of
robot troops that guard his research
bunker. If the reports on the strength of
these beasts, called Gormas, are true,
it's easy to see why those government
vapor-heads back on Centra are so
shaken. And the information that
they're conducting experiments on the
sand snake, indigenous to Alpha II, are
especially disquieting. Even without
controlled mutation, those creatures are
widely regarded as the most deadly ever
encountered in the universe. After all.
Alpha II is where the term "vicious as a
snake" first came into use among the
early explorers.
Your mission, as related by the GSS
bureau chief, is to gain entrance to Zar-
kon's stronghold, survive any encoun-
ters with the mutants and robot guards,
rescue Professor Smartguy and his
equipment, defeat the evil wizard, over-
load the nuclear reactor, and then steal
a spacecraft and escape before it ex-
plodes. Now, they certainly aren't ask-
ing for too much, are they? But afterall,
they did put their best agent on the job.
With courage and a lot of luck, you just
might be able to pull this one off.
Having finally reached a stable orbit
around Alpha 1 1, you glance at the small
chunk of rock and ice floating just out-
side the helm's viewport. It's hard to
imagine that this tiny, unimposing speck
of debris could harbor any tremendous
threat to the galaxy. You learned long
ago, though, that judging a situation by
appearances is fatal, all too often, in this
line of work.
With this pleasant thought swirling
through your mind, you energize the
transporter and step into the shimmer-
ing beam of light, remembering too late
that it has been malfunctioning lately,
and has acquired the nasty habit of
separating you from your weapons and
equipment during transport. As the
light flares and then dwindles to a glow,
the cabin is left in silence.
And the Adventure begins. . . .
Loading and Playing Instructions
Rescue On Alpha II is a graphics
Adventure requiring at least 32K of
RAM and Extended Color basic. If
you are entering the program from the
listing, it should be saved with CSA
VE" ALPHA //"before RUNning. After
that, the program can be loaded with
the CLOAD command; no other com-
mands are needed prior to loading. If
you have a disk drive, the program will
not run with the drive controller plugged
in.
Upon initialization, you will be asked
whether your machine can handle the
speed-up POKE, if it will, type'Y'and if
not. type "N\ If the answer is no, the
program will run a bit slower, but
nothing else is changed. If you answer
yes and have trouble with keyboard
response, rerun the program and change
your answer.
The program uses standard two-word
commands: a verb followed by a noun.
A multipurpose USE command takes
the place of most verbs when using an
object. For a list of verbs that the pro-
gram understands, you can take a peek
at Line 140 of the listing. Only one
abbreviated command is supported:
INV for an "inventory" of items that
you are carrying. Directional commands
must be entered in full, such as GO
SOUTH.
To win the game, you must locate the
professor and his equipment: a white
case, an instrument box, a chest and a
machine known as a Biotron. Then,
after pushing the self-destruct button in
the nuclear reactor room, you must
escape with the professor and his
equipment in the awaiting spaceship
before the reactor blows.
Sound easy enough? In this program
by Steven Mitchell, saving the galaxy
from evil is never easy.
— Kevin Nickols

'/ THOUGHT ONLY AN APPLE SOUNDED THAT GOOD'
That's what I was told after I gave a seminar and demonstration of MUSICA 2 and the STEREO
PAK at the Chicago Rainbowfest. I smiled and thanked the young man for the "supposed"
compliment, but upon reflection, I became angered by the apparent belief that the C0C0 is
inferior in this regard. Nothing could be further from the truth.
To help fight this false belief, we've decided to lower the price of MUSICA 2 until the end of the
year to help spread the word.
We will also keep the STEREO PAK price at S39.95 and give you a complete refund if you are
not 100% satisfied with the STEREO PAK.

STEREO PAK™
Plug this gem into your computer, connect to your home
stereo system and sit back and enjoy music realism. The
STEREO PAK is a hardware music synthesizer that plays our
MUSIC LIBRARY and MUSICA 2 music in stereo. Because it
was designed specifically with music reproduction in mind,
the sound is superb. The highs are crisp and clear while the
bass notes will rattle your walls.
The STEREO PAK is all hardware. It is intended as an
enhancement for MUSICA 2 and our MUSIC LIBRARY. Disk
owners may use the STEREO PAK with the R.S. Multi-Pak or
our Y-CABLE ($28.95)
^ MUSIC LIBRARY™ 3 VOLUMES
You get over 100 four voice songs with a combined
playing time of 3 hours. That's right, 3 hours of music. You
won't belive your CoCo could sound so good. To fit over
1 00 songs required both sides of 5 C-20 tapes and the disk
version uses 5 full disks (that's a half box of disks).
AJUKE BOXselection program is included to allow you to
select specific songs or automatically play each. These
songs are ready to go, you don't need MUSICA 2 or a
knowledge of music
These songs were developed using the best music program
available for the CoCo; MUSICA 2. The tunes may be used
as source files for MUSICA 2 and changed by the user.
When coupled with the STEREO PAK the songs are
reproduced in stereo with unsurpassed realism.

THE ROLLS ROYCE OF SPEECH SYNTHESIZERS
RICH PARRY
Voice Project Manager
In designing the first speech synthe-
sizer for the Color Computer, our
design goal was not to see how
cheap we could make it, but how
good. Perhaps we made it too good,
since the original price was well over
SI 50.00. We managed to reduce
the price to $79.95 without effecting
the quality. Unfortunately, we can't
keep it at this low price forever, but
we will until the end of the year. And
to entice you a little, we are going to
give you a FREE TALKING HEAD
program and any other piece of
software in ourTALKING SOFTWARE
LIBRARY FREE. Even TERMTALK
which sells for S49.95.
If you think we're bragging, listen to
our customers.
"Let me express my thoughts about the
VOICE. SUPER! GREAT! OUTSTANDING!
Ben Burnett
"/ found the VOICE is the best speech
synthesizer on the market for amateurs or
experts, in other words it's fantastic."
Deni Furnell
"The VOICE is really great"
Tim Rueb
"Congratulations on a really great superior
product. "
Leonard Hyre
• Onlythe VOICE willwork in both
the CoCo 1 and CoCo2 without
modification.
• Only the VOICE amplifies and
filters the speech to give you
increased intelligibility.
• Only the VOICE gives you a vol-
ume and pitch control for added
flexibility and sound effects.
• Only the VOICE has dual out-
puts. Listen through your TV
speaker or connect to your stereo
system.
• Only the VOICE is enclosed in a
metal case with a black satin
finish to eliminate TV interference.
FREE TRANSLATOR
A special ML "translation program" is
included free which automatically con-
verts English to speech. This program is
incredible. It not only speaks anything
you request, but even numbers such as
$12,234.55 are spoken in dollars and
cents. In addition, an "exception table"
option actually allows you to specify a
particular pronunciation if you like.
Writing your own BASIC programs to use
speech is a "piece of cake". Just change
your PRINT statements to USR.
A very special feature allows all text that
is sent to the screen to be spoken. Thus a
blind person can actually write programs.
You'll be amazed!
STILL UNDECIDED?

make programs easier lo read and Follow. However,
ihe REM, title should never be the line referenced by

ADVENT RE CONTEST WINNER
BEST OF
BEAST
Program By Mark Nelson
Deep in thought, Jon stepped
through the doorway of the
small, moss-covered cabin. The
cold, damp fog fled before him as the
warm air inside burst out into the night.
He could barely distinguish the edge of
the forest that surrounded him, but he
didn't need to see it clearly to know where
every tree stood, where every vine hung.
Wilmouth Forest was the only world he
had ever known, and he knew it well.
The cool night air and the familiar sight
of the forest brought a torrent of memo-
ries rushing to the surface of his troubled
mind —memories that he had been able
to put aside for the past two years. Had it
been that long? Had it been two whole
years since he had last hunted game in the
forest at his father's side — since his
mother and father had walked happily
into the forest and never returned? What
unspeakable fate had befallen them? It
was difficult to examine these questions
without tears welling up in the young
man's eyes.
But it was time, and time past for such
examination. The world that Jon once
knew in the peaceful confines of Wil-
mouth Forest existed no longer. It had
become foul and obscene. Where once
roamed brave and noble knights along
the byways, now skulked only base crim-
inals pretending to be the knights they
(Mark Nelson, a computer science student at
Utah Technical College, also works as the
head of the computer department in a local
electronics store. This is his first published
program.)
had once cowered before. Where once
young maidens had gathered mushrooms
from the dawn-streaked, dew-stippled
forest floor, hags now collected dung and
rotting matter for their vile concoctions.
And where once could be found hart and
boar to rival any in the land, only the
most unearthly creatures were now re-
ported by those fortunate enough to see
them in time to escape unscathed.
Evil begets evil; so it is and so it has
always been. And all of the evil now en-
sconced in the boughs of the woods could
be traced to a single cause: The coming of
The Beast to Wilmouth Forest. From
that day hence, joy and peace were known
no more in the Kingdom of Daethnon.
Jon knew of The Beast only by the
terrified tales of those who happened to
stumble into the clearing surrounding his
hut, clawed and mangled and beyond
wit's bounds. He himself had scarcely
gone beyond the outlying trees since his
parents had fallen victim to the shadows
beyond, and not once had he ventured
outside the hut after nightfall. But this
fact alone spoke no ill of the young man.
The tales and the sight of those unfortu-
nate souls were enough to paralyze even
the stoutest heart.
Tonight, though, a new resolve had
come over Jon in his solitude. Shaking off
the bonds of fear, he had thrown open the
door of the hovel and taken the first brave
steps into the night. No more would he
cower before the fire, held prisoner by an
unseen and nameless terror. And no more
would he allow the death of his parents to
go unavenged.
THE RAINBOW December 1984
December 1984 THE RAINBOW
As Jon turned to go inside, he heard
something come crashing through the
undergrowth just beyond the first stand
of trees. Reaching lor his knife, he saw a
horse and rider bound into the clearing
and twirl once before the mount could
be brought to rein.
Mustering his courage, Jon stepped
into the shaft of light emanating from
the doorway. With knife drawn, he
stood before the lathering steed. "Hail,
fellow." he challenged. "If thee come for
solace, then well met. But if thee have
mischief in mind, prepare thyself."
"1 seek no mischief," the rider re-
sponded in shaken tones. "Sheathe thy
blade and bid welcome to a messenger
of the king."
"What herald could be of such import
as to bring thee through this evil forest
at night?" Jon queried as he grabbed the
reins and cautiously helped the rider
dismount. "Does the King of Daethnon
care no more for thee and th\ fellows
than to spend thy lives for a message'.'"
"Well met, indeed," replied the rider,
"and well spoken. Were that I were in
thy charge instead. But mine sire is not
so callous. These evil times bode ill for
all men. whether they ride or hide. Dan-
gerous times warrant dangerous acts."
"Verily, thou dost echo mine own
thoughts." said Jon. "Speak then thy
message, herald, that I may judge its
import for mineself."
Reaching into the leather pouch swung
over his shoulder, the rider pulled forth
a rolled parchment, tied in the center
with a golden ribbon that caught the
dim starlight, flashing brightly. Unroll-
ing the document, he rose to his full
stature and read: "Know ye people
throughout the realm that by these
presents. His Majesty, the King of
Daethnon, doth hereby proclaim that
whosoever slaycth the beast that dwel-
leth in the Forest of Wilmouth, and
further, that bringeth the head of this
beast before His Royal Highness, shalt
be rewarded for his service to the crown
the hand of the Princess Shcra in mar-
riage and one quarter of all the lands of
the Kingdom of Daethnon."
Awestruck. Jon stumbled against the
side of the horse before clutching the
stirrup and catching his balance. It was
an omen, he thought — an omen of
fortune in a time where the word no
longer held meaning.
"I accept this charge." he bellowed,
"for surely, it doth suit my purpose. Ver-
ily. I shalt seek out this demon and send
it back to the netherworld from which it
was spawned."
Whirling around, Jon strode into the
cabin, grabbed his pack and bow, and
extinguished the tiny lamp on the table.
Without a glance, he walked back
through the doorway for the last time
and headed for the clearing's edge.
As the morning light began filtering
over the treetops from the east, the mes-
senger called after him as he disap-
peared into the brush. "Well met, indeed,
sire, and may we soon meet again.
Know ye that the prayers of all the
realm go with thee."
Loading and Playing Instructions
The Head of the Beast is a fairly
unusual Adventure in that a joystick is
used to enter all commands. Originally
intended for 32K Extended basic, it is
easily adapted to I6K ECB. with the
only sacrifice being the game-save rou-
tine.
if you are entering the program from
the listing into a 32K or 64K ECB
machine, no changes need to be made.
Simply save the game with CSA VE
"BEAST". Afterward, the program can
be loaded with CLOAD and no other
commands are necessary.
7 o enter the program from the listing
into a I6K ECB machine, first enter
POKE 25,6. Then omit Lines 3000-3070

The program can then be saved in the
usual manner. Thereafter, when loading
the game, enter POKE 25.6 before
CLOA Ding.
If you subscribe to RAINBOW ON I APE.

The program is now modified to run in
I6K of RAM and should be saved on
tape before playing. As before. POKE
25.6 must be entered each time there-
after before loading.
To play The Head of the Beast, you
must have a joystick plugged into the
right joystick port. The commands are
selected by moving the cursor with the
joystick until the desired command is
highlighted and then pressing the fire
button. When a verb is selected, the
words on the screen are replaced by a
group of nouns. Movement is accomp-
lished in the same manner, with per-
missible directions surrounded by black
bars.
If you are using the 32K version with
the game-save routine, you may save
your game position by moving the cur-
sor to the word TA r°£"and pressing the
joystick fire button. Then move to the
word SA VE. press the lire button, and
press the Play and Record buttons on
the cassette recorder. When prompted,
enter a filename of up to eight letters
and hit I Ml R. The game can then be
loaded in the same manner, returning to
the position in the game where the save
was made.
You're now ready to engage The
Beast. And remember, in this Adven-
ture by Mark Nelson, a princess awaits
your triumph.

CoCo Tuner"
D Makes tuning musical
instruments a breeze!
□ Precise enough for concert
piano tuning.
D Easy to use for music students
and teachers.
Al last, Ihe all electronic equivalent ol the Strobotuner" is now
available for your CoCo. The CoCoTuner is a plug-in module lor
the Color Computer' By plugging a microphone into this
module (a sensitive preamp is built in) you enable the CoCoTuner
to display a pitch comparison Bands on Ihe screen move to the
right il the note is too sharp and left if it is too flat You can ad|ust
for a true "zero beat" to the internally generated pitch, which is
accurate to within 003 Hz at middle C This precise pitch is also
available through the TV speaker so you can hear the pitch com-
parison as well as see it Easy single-keystroke commands
change notes tor fast operation Standard pitch is A-440. For
non-standard tuning, a percentage offset factor may also be
specified at your keyboard For non-musical applications, you
may even specify frequency to within 01 Hz.
The CoCoTuner needs only a reasonably good microphone with
a standard Va " plug If you are going to use the CoCoTuner for
piano tuning, we offer a companion piano tuning kit (professional
tuning wrench, 4 mutes, temperment felt . and a booklet "How to
Tune Pianos Electronically")

ORDER ENTRY SYSTEM
Rainbow, Feb. '84 "If you are looking for a program to keep track of your sales and print
invoices, then this one will take care of those needs quite well.. .A good program that
would serve the invoicing needs of a small company quite nicely."
The Mark Data Products sales order processing system provides a fast, efficient means to
enter orders, print shipping papers and invoices, prepare sales reports, and monitor
receivables. The system automatically enhances the monitor screen to a 51 character by 24
line display. 32K of memory is required along with an 80-column printer and one or more
disc drives.
The MDP Order Entry System is a family of programs which operate interactively by means
of a "menu" selection scheme. Up to 900 products may be defined and a single disc system
can hold over 600 transactions. When the operator selects a task to be performed, the
computer loads a program designed to handle that task from the system disc. The system
disc contains all of the programs required to create, update and maintain data files and
prepare the necessary paperwork including shipping and invoice forms, daily sales
reports, a monthly (or other period) sales report and a receivables report.
This order entry software equals or exceeds higher priced packages for other computers

FEELING
HELPLESS?
YOU NEED TO
LEARN A
LESSON !
MICRO LANGUAGE LAB ■
LEARNING THE 6809
F_ eeling at the mercy of a program-
I mer somewhere ? Mystified by a
machine? My Micro Language Lab
will give you the power to end
those helpless feelings.
Here's why. The heart of any com-
puter program anywhere is machine
language. Every piece of software uses it
— your favorite game, spreadsheet,
word processor, data base manager, or
recipe file. Every time you hit "Enter ",
it's working. All the languages and
operating systems are created from it.
Basic, Fortran, Pascal, Flex, OS-9,
TRSDOS . . . they're 6809 machine
language, the whole lot!
And you can learn the language of
the 6809, the programming heart of
your Color Computer, with my Micro
Language Lab.
Not everyone can program. Writing a
few lines in Basic now and then doesn't
make you a programmer. But if you can
program, then my Micro Language Lab
will teach you — the right stuff, the
right way.
I'll teach you in 24 half-hour lessons
on 12 audio cassettes, with a 220-page
textbook, with data booklets, with 35
sample programs, and with a program-
ming reference card. You'll spend 50
hours or more with my course, listen-
ing, watching, and working. And when
you're done, you'll be programming
your Color Computer in the 6809's
language.
Stop ignoring those gnawing feelings
of helplessness. The 6809 is where the
power lies in your computer. Turn on
that power with the Micro Language
Lab.

Football Fever
Part 2
By Fred B. Scerbo
Rainbow Contributing Editor
(Editors Note: If you have an idea for
the " Wishing Well, " submit it to Fred
c/o THE RAIN BOH: Remember, keep
your ideas specific, but don 't forget that
this is BASIC. All programs resulting
from your wishes are for your use but
remain the property of the author.)
Here we are one full month later,
and by now, I hope most of you
have been able to figure out my
new method of generating additional
colors for your PMODE 4 screens. I
know it was cruel to keep you waiting
for another month to get the technique
fully explained but as I mentioned last
month, a careful examination of the TV
screen should have been able to give you
an idea as to how this works. Shortly, I
will put together a set of these routines
which you can use in your own pro-
grams with the greatest of ease. That
will come in an upcoming "Wishing
Well."
if you typed in last month's "Wishing
Well," you have already gotten some of
the same type of graphics which ap-
peared in Roc kf est and Baseball Fever.
As I have mentioned over and over
(Fred Scerbo is a special needs instruc-
tor for the North Adams Public
Schools. He holds a master 's in educa-
tion and published some of the first
software available for the Color Com-
puter through his software firm. Illus-
trated Memory Banks.)
again in these pages, I know of no
greater way to learn programming,
especially color graphics in Extended
Color BASIC, than to key in programs
such as these. This can be especially valu-
able and personally rewarding to high
school and middle school students to
get these kinds of graphics results. This
can provide a spark of motivation for
these young programmers to create their
own works of art on the computer
screen.
Since last month we had only the
National Football Conference teams in
part one, this month's version deals with
all the American Football Conference
teams. To be perfectly honest with you,
these were much easier to create than
last month's. (The most difficult this
time around were New England and Los
Angeles.) Another thing that made this
version a little easier was that 1 could
use about 25 percent of part one in part
two, such as the coloring routines, the
helmet shells, and the screen quiz and
character sets.
If, when typing in this program, you
wish to use some of the lines from the
first part, you may use the following line
sections without any changes:
Lines 30-130
Lines 160-210
Lines 250-300
Lines 5000-5340
Lines 5360-5670
If you delete all lines but these, and
insert the newer lines as needed, you will
save some time. The other lines, while
they may look similar, really have to be
keyed in by hand. ( Better yet, RAINBOW
ON TAPE is really valuable in a case like
this.)
Most of the routines for painting
and drawing the helmet shells
remain the same in concept; I have done
a little tinkering in a few cases. Take, for
instance, the use of the POKE178,n
which gives us some additional colors in
a striped pattern. 1 only used this POKE
once in both programs to generate green.
It seems that green has been the one
color which I have had the most diffi-
culty with in PMODE 4. You might
wonder why in these cases I just didn't
draw these helmets in PMODE 3. Nor-
mally. I would, as I did with the symbol
for the Brewers in Baseball Fever. How-
ever, since these programs incorporate
the screen qui? which really needs the
PMODE 4 resolution for the screen text
characters, the use of PMODE 3 would
make some of these Hi-Res characters
unreadable.
To compensate for this, 1 slightly
modified Lines 140 and 150 in Part 2 to
include a variable ZZ which would be
included in the POKEI78 variable. Since
I have allowed you to assign the red-
blue values from the keyboard instead
of hitting the Reset key. the POKE! 78 is

RED

not as easily controlled by this change
from the keyboard. Thus, the use of the
ZZ variable has allowed me to get much
closer when the alternate red-blue assign-
ments are chosen. (This was not exactly
the case in Part l when painting the
green for the Eagles, whose helmet
might sometimes come out more on the
gray side.) Hopefully, this adjustment
will solve that problem for you.
Keep in mind that the colors for these
helmets will not be exactly as you see
them in real life or in the pages of Sports
Illustrated. However, in most cases they
will be close enough for you to identify
who the teams are and impress your
friends with another CoCo graphics
achievement.
The Big Secret
Now let's get down to the part you've
all been waiting for. How are we getting
these extra colors?
A close examination of the screen will
show you that most of these colors are
being generated in a checkerboard style
fashion. We actually get down to setting
individual pixels using a counting loop.
As you are by now aware, when we get
red or blue in PMODE4, it is because
we have a case of alternate pixels being
turned on and off. Therefore, a row of
pixels set in the pattern of ON/ OFF
/ON/OFF/ON/OFF would actually
give us what appears to be a solid field
or line of either red or blue. If we set two
adjacent pixels as ON/ ON, the result
will be a solid double pixel of white.
Two adjoining pixels set OFF/ OFF will
result in a double solid pixel of black.
Take a look at Figure I. This is the
pixel pattern which I have set to simu-
late the color yellow, assuming we know
the result of a given pixel in red or blue.
(This pattern, offset by one pixel, will
create a light blue pattern.) The pattern
we create with the pixels results in se-
quences of OFF/ ON/ ON/ ON. The vis-
ual result is to have a black pixel, a red
pixel and two white pixels. The row
below is set in the same fashion offset by
two pixels giving us our checkerboard
pattern. Therefore, the result of red sit-
ting next to white is to give us a visual
yellow in our checkerboard pattern.
Let's try another color. We know we
can easily generate either red or blue. If
you were using real paint and only had
red and blue, how would you go about
getting the color purple? Naturally, you
would mix the red and blue to create the
purple. Why not do the same with our
screen to get purple? Check Figure 2. By
setting rows of red pixels with a row of
blue pixels below, our screen result will
give us a purple hue, in a semi-checker-
board pattern.
While the actual pixel grid shown in
Figure 2 will result in a very light purple,
the actual version in the program uses
half as many red pixels (every fourth
instead of every other pixel turned on).
Still, the illustration serves our purpose.
A check of the arrays will indicate
that patterns have also been generated
for a silver and gold as well. The silver
alternates white pixel blocks and later
combines with a blue array to give us
our shades of silver or silver-blue. The
gold is achieved much like the yellow
only half as many red pixels are used.
Depending on how your set is adjusted,
the gold may appear more like orange.
Once we have generated these color
strips which are two pixels deep,
they are stored in an array by using the
G£7"command. (The graphics screen is
turned off while this occurs so we don't
have to watch the strips being drawn. If
you would like to see the strips being
drawn, change the SCREEN command
in Line 1 70 to SCREEN 1,1. Be sure to
change it back for your final copy.)
Once we have the strips stored in their
arrays, we can paint them back on the
screen using the PUTcommand. Since
our strip is only two pixels deep, by
usinga FOR. . . iV£ATloop, we can fill
any part of the screen by setting up a
loop to cover those coordinates.
One small problem exists, however. If
we use the PUTcommand as most pro-
grammers are accustomed to using it,
the strips will simply mask out any area
we have drawn on our screen. This can
be solved by using the OR command
with PUT, rather than PSET or
PRESET. The way in which OR works
is that if a pixel is not turned on (i.e.,
black), then the contets of our Get array
will appear wherever the pixels are
turned off. If a pixel is turned on, that
area will remain as it presently is.
Therefore, if we wish to paint an area
yellow, we should first draw out the area
we wish to appear as yellow and paint it
black. Then, by using the FOR . . .
NEXT loops and the PUT command,
we will fill in only that black area with
our yellow array.
There are a few limitations, however.

We always must paint our array colors
first, or they might reset a red or blue
area. Often, you can use only one of
these array colors at once, unless you
have arranged your screen so that the
arrays never overlap.
To get a better idea of how this is
working, take a look at Figure 3. Here
we have the makings of the helmet for
Seattle. Since we wish to paint in silver,
we have made the total helmet area
black, and then overlay it with our silver
array using PUT and OR. Notice that
the Seahawk has been left completely
white, to be colored in later with our
regular PAINT Colors.
You may ask: If you can get yellow
and can paint blue, why can't you mix
the yellow and blue to make a real
green? Well, to be honest with you, I
have tried that and it does not seem to
work very well. Apparently, you can
stretch these combinations only so far
before you start getting messy.
This technique is not restricted to
PMODE 4. You can try this method
with your PMODE 3 color set. You will
get some other variations, but I think
that you will agree that the PMODE 4
set with black and white is something we
have grown very used to.
Try this version, and remember —
you must select either the eight or the
four in the "84" depending on which
number is red. You may wish to try
some screen dumps although you will
not get these new colors on the color ink
jet sprayer since combining blue, red,
and white ink will not create yellow no
matter how hard you try.
Some of you may want to try to
merge parts one and two to have all 28
helmets in one program. This is not
impossible, as you should have enough
memory. You will run into a problem
with the screen quiz section and the data
since some city names have more than
one team. Still, with a little effort I'm
sure you can come up with a way. (Sure,
I could tell you how, but you would
never learn how to do any of this your-
self if I did.)
For 16K
Those of you who want shorter ver-
sions can try typing in just the lines for
each helmet. There is one catch. You
must include Lines 70-200, and Lines
540-580 as well as any other subroutines
which a given helmet might use. (You'll
be able to tell when you are missing
one.) Also include:
210 GOTO 600
This will prevent you from running
into the subroutines. If you must in-
clude other subroutines, jump over them
with a GOTO statement.
Maybe some of this is getting to be
old hat, but fortunately, these helmets
were not as tough as Baseball Fever or
Rockfest. The sequels to those pro-
grams are in their formative stages now.
I am planning at least another graphics
treat before 1 return to a few educa-
tional applications which so many of
you have written to me about.
I have one final request, however.
Many of you have written me with pro-
gram lists and SASEs asking to help
you try to find the bug you have made
typing in the programs appearing in the
"Wishing Well." I know that the inclu-
sion of a SASE does tend to obligate me
to some type of reply, but there have
been so many requests like this that if I
were to try to answer them, I would
have no time to create each month's
program(s). There have been no bugs in
any of these listings yet. Any errors I
have seen submitted to me have always
been typing errors on your part. There-
fore, if you can't find your bugs, you will
get much quicker results by getting
rainbow on tape. I don't mean to keep
pushing this issue but there is really no
better deal available. You will find that
your time is most certainly worth the
few dollars it would cost per month to
get a subscription. Then you know you
will be getting bug-free versions.
Until next month, Merry Christmas.
Happy Hanukkah and a Happy New
Year to all of you.

Dungeons & Dragons Best Of Show goes to Eric and
Mark Riel of Kent, Wash., for The Halls Of Dungeon
Death. This fine little program combines features of arcade
graphics and cursor movement with the more common
Adventure commands. With enough machine language rou-
tines to make the program extremely fast, it remains exciting
for as long as the player can hang onto the keyboard. Also, it
features one of the best graphics title screens of all the
contest entries.
Non-Graphics Best Of Show And Third Place Award
goes to Gregory Clark of Syracuse, N.Y., for his two entries,
Kragnor & Flodnar and Sir Ranclolf Returns. Both pro-
grams were so good and, also, so similar in several respects,
that the judges could not separate the two. (So similar, in
fact, that Flodnar is Randolf spelled backwards!) Greg's
name manages to crop up among the winners in every con-
test held by THE RAINBOW. He and Sir Randolf took the
non-graphics top award in last year's Adventure contest and
he also made a respectable showing in the first Simulation
contest, winning an award for his program, Flood. In Greg's
games, you can always expect the unexpected. For instance,
Kragnor & Flodnar begins in a store where purchases must
be made among more than 100 items. How's that forgetting
a game off to a complex start?
Graphics Runner- Up And Second Place Award goes to
Carmen DiMichele of Linwood, N.J., for Castle Thuudo.
This is a disk-based Adventure that accesses the disk for
each and every graphics picture. If you have not upgraded to
disk drives yet, this program alone should be enough to spur
you to the purchase. In the quest to discover and defeat the
evil Thuudo, leader of the gods, you will encounter breath-
taking graphics screens at every turn. And the final battle
with evil is one you will never forget.
Graphics Best Of Show And Grand Prize is presented to
an Adventure that has it all: Rescue On Alpha //, by Steven
Mitchell of Tomahawk. Wis. This game has enough daz-
zling graphics and random elements that even the most
experienced Adventurer should find it challenging time after
time. As befits an Adventure of this magnitude, no mere
kingdom or treasure is at stake, but rather the entire galaxy.
Seriously, this game has so many things going on that it
causes a minor problem; if you leave the game sitting
untouched for a couple of hours, it will run itself out of
memory. Of course, chances are that one of the roving killer
robots will finish you off long before that happens. In this
program, the Adventure continues even while the player is
taking a break.
I wish that it were possible to mention all the entries that
showed promise, yet were ruled out for one reason or
another. It was a terribly, terribly difficult process choosing
these winners from the field and the judges sincerely hope
that we have done them all the justice that they each deserve.
For now. though, let's move on to Rescue On Alpha //and
The Head Of The Beast to see a couple of fine examples of
what The Second Annual Rainbow Adventure Contest has
produced.

BITS AND BYTES OF BASIC
// O routine and data entry modes
Rainbow Checkbook IV
By Richard White
Rainbow Contributing Editor
In this issue we will cover the I/O routine and date entry
modes. In previous months, we have covered a lot of
code, much in subroutines, but have not seemed to cover
as many program functions as 1 might have wished. Now, we
will move a bit faster since many of the needed subroutines
are complete.
At this stage of program development, the I/O routines
are particularly important. They will allow us to type in a
test file once, save it. and then reload it again and again as we
exercise the program to find the bugs. If you are working
with a cassette, make eight or 10 copies of the test file on a
tape so you don't have to stop and rewind as often.
I always put my primary I/O routines in the 900 block of
lines. Save routines come first, then load routines and finally
any subroutines that are used by load and save. This way
there is never a need to hunt through a listing to see where
these are.

Line 900 prints a menu that gives a user the choice of tape,
disk or printer output. The variable D is used to carry the
buffer number, -1 if tape or I if disk. If Pis keyed for printer,
the program is sent to Line 600 and no buffer number is set.
(Richard While has a long background with micro-
computers and specializes in BASIC programming.
With Don Dollherg. he is the author of the TIMS data-
base management program.)
The menu is user-proofed in that it starts over if any key
other that T, D or P is entered. Note that spacing of lines is
done using a series of commas. Each pair advances the print
position one line on the screen. It's as quick and economical
as any other way to advance two or three lines. We use our
friendly GOSUBI to call the INKEYS routine in that line.
Line 910 is all the code we need to save a file once it calls a
subroutine starting at line 985, which we will examine first.

995 LINEINPUTI»:IFI$<>"THENNH«=I*:RETURNELSE
RETURN
In Line 985, D is tested to see if tape or disk mode had
been chosen and TAPE FILE or DISK FILE is printed
accordingly. Line 990 then asks for the filename, prints
AND EXTENTION if disk is chosen and then prints the
current file name. If you are using the default extension,
DAT, it need not be entered. If you had previously loaded a
file, NM$ contains the name of that file. You may reuse it,
that is, replace the existing file on your disk with youi
updated check file or save it as a new file to another disk that
does not have that filename. You have essentially the same
options when using tape. We have seen the method in Line
995 before where LINE/NPUTIS asks for a string. Only if
characters are entered are l$'s contents assigned to NMS. By
the way, I use LINEINPUTIS here so disk users can enter a
drive number if they want. For example, to call a file call
TEST/ DAT in drive one, TEST:! can be entered. INPUT
treats the colon like it does a comma and figures that the

Having handled the filename matter with the GOSUB985
call. Line 910 proceeds to open the file using the variables D
and N MS. CoCo BASIC was a step forward in the simplifica-
tion of file handling routines based on string or numeric
variables such that the same code can address a variety of
devices. Microsoft has further developed this concept in the
IBM and Radio Shack Model 100 BASICS. After opening the
file for output, OPEN"0".... we print LR, the last record
number plus one, the bank balance BB and the current
balance CB so these will be at hand after we load the file.
Next a FOR. ..TO.. .NEXT loop is used to save the data
arrays A$(X). A(X.0)and A(X,I). Since LR is the number of
records plus one, the loop is made to end at LR-I . The file is
then closed and control returns to the calling routine.

965 RETURN
Loading a file back in follows the saving pattern almost
exactly. Line 950 is the tape or disk choice menu. In Line
960. the file name function, file opening and data recovery
are nearly identical to Line 9 1 0. The file is opened for input
OPEN "J". ■ ■ rather than for output. The keyword INPUT
is substituted for PRINTand that's it until the code after the
CLOSE.
You may remember that we defined an A$(0) array that
contained the note FIRST ENTRY BELOW. This message
appears when the user scrolls back to the first entry. The
associated numeric arrays for amount and balance were not
assigned data. While working on the editor. I realized a
balance would be needed in A(0.l) if a new entry were
inserted as the first one in the file. Further, when cleared
items are stripped from the file, the first entry will change
and the balance in A(0,I) must change. For now, calculating
A(0.1) when a file is loaded handles the matter, particularly
since the zero arrays are not saved to the file.
Note that this zero balance must be calculated in one of
two ways, depending on whether the first record is a deposit
or other type. For a deposit, the amount, A(1.0) must be
subtracted from the balance A(l.l)\.o get A(0.1). Otherwise,
it is added.
In normal operation, a load or new menu at Line 2100
sends the program to load a file and then to the input mode
starting at Line 100 to perform the various inputting and
editing operations.

First, a new printing position variable. PS, is defined.
Next, subroutines 50. 52. 54 and 56 write the fixed text on
the screen. A STRING$(192.32) cleans the variable data
area. CR=LR in the expectation that the user will be enter-
ing a new record. Subroutines 12 and 1 1 get the data for
record CR-1 and print it in the top record position. Fl is
used as a flag to signal subroutine 1 4 to do a return after the
last record variables are put into the current record varia-
bles. Fl is set to zero after the GOSUB14. The current
record variables need to initially contain the last record
values so the user can reuse these if they wish. Line 14 was
changed to permit its use here so, if you have been typing
along with us, you had better correct 14 now.

Let's come back to the PS variable. When 1 wrote the
editor code. I found that I wanted to write the current record
starting at position 96 rather than at 224 as we have up to
now. 1 found that if I changed Line 15 using PS and an offset
value 1 could use that subroutine from both data entry and
edit modes. Of course this means that PS must be set at a
number of places in the program and we will point it out
when it appears. In the meantime, here are the lines we
discussed previously, as changed.

You probably noticed the similarities between 2 1 30 where
PS=PO was added and 1 10, our new input mode line. Most
of the 100 block is identical or very similar to the 2125-2160
block, so I will review the functions and comment only on
significant differences. Line 120 tests for data input mode.
FG=0 and entry of a digit or a carriage return. These condi-
tions satisfied, it goes to Line 60 where a series of subroutine
calls step through entry of a new check. If these conditions
are not satisfied, control falls through to Line 1 30 where the
IS is tested against the string "DAVCESLN"+CHR$
(94yrCHR$(IO). The user was previously prompted for a
keystroke by text printed by Line 56. Compare the function
names in Line 56 with the characters in the search string in
130.

If a match between IS and a character in the search string
in Line 130 is found, .1 will be assigned the character's
position number in the search string. Control will be passed
to one of the lines after one of the ONJ GOSUBs. One
GOSUBis used from the input mode when FG=0. The other
is used when in the scrolling mode to keep the user from
inadvertently choosing a function that could destroy data in
the file.

160 CS$="C" : GQSUB15: GQSUB38: RETURN
Returning from a subroutine call in Line 130. Line 140
checks to see if the program went to a routine that changed
the screen. If so, the program is sent to 100 where the input
mode starts from scratch. Line 150 tests if the user has
scrolled to the top of the file and should be put into input
mode in Line 1 10 or be left in the review mode and sent to
Line 120. Line 160 clears an item, reprints the entry and
updates the AS(CR) entry. If you incorrectly clear an item,
you can go to edit mode to correct the error.
Once the 1/ O and input code was finished. I could load a
test file and really start exercising the program. Gone were
the days when a syntax error meant retyping entries to test
the program. Most of the serious errors had been found
before this. At this point, the programmer becomes aware of
the small details like a misspelled word or the improper
location of text on the screen. A case in point was Line 1 1
which printed the date for the last record one space too far
left. A space was added to the spacer stringjust before LDS.

Next I found that 1 was not returning to the entry mode
from the scrolling mode. I thought I had that working right
in the new file mode. It turned out that the Line 40 subrou-
tine call did an LR=CR that caused confusing things to
happen. The solution was to drop the subroutine call and
put the proper call in Line 18 itself. The corrected line
appears below.

cannot seem to remember to put a space between a variable

thinks it is dealing with a long variable name and does not
recognize in this case the THEN. Moving on, I changed the
logic in Line 36 to make the balance-updating work prop-
erly. Note that there is a variable and a following keyword.
ELSE, in this line also.
36 IFCMO'DEP'THENCB-CB-CA ELSECB-CB+CA
68 PRINT8320, "REVIEW ENTRIES "C
PO-339: FB-1 : 8QSUB17:RETURN
It's a little thing, but the string of spaces after REVIEW
ENTRIES in Line 68 was one short of enough to completely
erase the previous printing. Nine spaces will do the job.
After the I/O code was complete, the way the entry menu
handled a return from loading a file to get the user to Line
100 needed work. The problem was that 1 wrote I/O
handlers as subroutines and Line 21 10 sent the program
with a THEN950. hardly a subroutine call. Of course, if a
subroutine call is used, control will be returned to the code
following the subroutine call and here is where a GOTOI00
must be added to get to the input code. The corrected code
follows.

In 2050. SNS was changed to "% %"and CSS was initial-
ized to "O" instead of "OUTSTD" to provide for more note
room. Also in Line 2050 was the string ISS which was
intended to be a standard string to search for IS in an /NSTR
statement. Since 1 have not used it. it was deleted.

Finally some surgery was performed on Lines 2 1 50-2 1 55.
Line 2155 was renumbered to 2157 and a new Line 2155
added. Essentially it sends the program to the input mode
when a SA VE'xs requested. Once the user has saved a file. I
expect them to operate from the input rather that the new
file mode. This way, return from the I/O routine is to the
input mode so the user can do more work if he or she
chooses. In Line 2150, the variable holding the I NSTR value
Was changed from I to J to be consistant throughout the
program.
The end is in sight. Three blocks of code remain; edit,
print and strip cleared entries to an archive file — 1 call this
NEW MONTH on the input menu. Edit is done, as compli-
cated as I expected, and will be a column in itself. The
printer is not written. If it's done in time, I will try to get the
complete program listed in the next issue and in RAINBOW
ON TAPE. j?s.

TURN PAGE FOR OUR NEW CATALOG
RADIO SHACK has been kind enough
to provide us with the following items of
interest regarding the Color Computer:
• Two packages, Graphics Pak (Cat.
No. 26-3 1 57) and Disk Graphics (Cat.
No 26-3251), are not recommended for
use with the DM P- 1 20 printer. How-
ever, they will work with the DMP-100,
DMP-110, DMP-200, CGP-115 and
the CGP-220 (black and white mode).
• Before using the Hi- Res Screen Print
Utility (Cat. No. 26-3121), Graphics
Pak or Disk Graphics with the DMP-
110 printer, you must put the printer
into elongation mode:
PRlNT#-2, CHR$(27)+CHR$(14)
This allows you to print across the
entire page rather than just half the
width of your page.
• In order to have access to Color Pro-
file from Color Scripsit, you must create
a spool file in Color Profile with the
print to disk option (Option 3). After
copying the file onto the Color Scripsit
disk, you may then access the file and
edit it.
• Recently released is TRS-80 Color
Computer and MC-10 Programs (Cat.
No. 26-3195), by William Barden. This
new book contains educational, word
processing, graphics and household
management programs for the MC-10
and Color Computers. Some of these
programs make function calls (i.e.,
COS, SQR and TAN) which are not
available under Standard Color BASIC.
Therefore, CoCo owners who have not
yet upgraded to Extended Color BASIC
can add the appropriate subroutines
which are given on Pages 287 through
290 of Getting Started With Color
BASIC. MC-10 owners will not have to
make any modifications.
• Radio Shack has an upgrade availa-
ble for OS-9 users: OS-9 Version 1 .0 1 .00
(Cat. No. 700-2330, $14.95). This new
130 THE RAINBOW December 1984
version has added new display control
codes for the video display. It also has a
driver for the Deluxe RS-232 Program
Pak and allows those in Europe to patch
their clock module to 50 Hz.
• The OS-9 C-Compiler (Cat. No. 26-
3038) requires a minimum of two drives.
C programs must be entered in lower-
case using the OS-9 editor. Each file to
be compiled must reside on the Library
disk. If you need more information on
compiling C programs, detailed infor-
mation can be requested from Radio
Shack.
• If you want to be in lowercase mode
when booting up on OS-9, put the fol-
lowing command in your STARTUP
file:
TMODE.l-UPC
• Color Computer owners who want a
white Drive I for their white Color
Computers may purchase the External
Drive 3 for the Model 4 (Cat. No.
26-H6I).
• If anyone is having a problem with
the Template program (Appendix E) in
the owner's manual for the X-Pad (Cat.
No. 26- 1 1 96), check the following line:
380 ON S GOSUB 2900, 2900, 530,

Note: The X-Pad is not compatible
with the Color Computer 2 for the same
reason that the old gray drives will not
work with the CoCo 2. The Multi-Pak

CoCo
Season's Greeting
Cards
By Francis S. Kalinowski
Would you like to amaze and
please your friends with com-
puterized multicolor season's
greeting cards next Christmas'? Surprise!
You can do it easily.
Here is a CoCo program that prints
personalized cards in five colors on con-
tinuous fanfold sheets. It can print on
any Epson printer with Graftrax-Plus
(including the FX-80), and on Gemini-
10X or -I5X printers. You'll have to
handle the paper, change color ribbons,
then fold and trim the individual cards.
I'll tell you exactly how to do all that.
Your CoCo, my program, and the print-
( Francis S. Kalinowski is a retired
commercial and military electron-
ics equipment handbook technical
writer [21 years]. He has had sev-
eral home computer articles and
programs published in various
computer magazines.)
er will do the rest. With color ribbons
available for Epson and Gemini print-
ers, you just can't pass up an offer like
this.'
The card program requires 21970
memory bytes for program storage plus
2650 bytes for strings and variable
records. The program runs in a 32K
Extended Color BASIC CoCo tape or
disk system cleared to one graphics
page, using PC LEAR I.
Displayed prompts ask for number of
cards requested, sender's name, and
card-printing credit name. The program
puts both names on each card during
printout. You may choose to print up to
25 cards in one printing session. Figure
I shows a printed card sheet ready for
folding and trimming. Fold and trim
lines do not appear on printed card
sheets.
1 sketched the card's cover art on a
layout sheet then turned it upside down
for coding. Cover art prints inverted in
the fanfold sheet's upper-left quarter
while greeting text portions print nor-
mally in the lower-left quarter during
five color print runs. A sixth print run,
with paper strip ends reversed, prints
the card credit. You may use any color
for the credit print run.
I used direct coding for dot-graphics
similar to that described in my Graftrax
art palette article (80 Micro Nov. "83).
Briefly, two-character string codes re-
present most of the 256 printable dot-
column patterns, similar pattern groups,
and printer mode control commands. I
did not define codes for 83 of the 90
ASCII values from 32 through 122.
When needed in a printing statement's
graphics segment, 1 use an undefined
dot-column pattern's equivalent ASCII
value character within quotation marks.
Single-letter strings AS through NS
represent some dot-column pairs to
December 1984 THE RAINBOW 131
simplify coding in 960-mode (double
density) graphics segments. Program
Lines 9060-9200 define the above global
string codes. Other single-letter string
codes represent multiple code patterns
used several times during a color print
run. I define these local codes in each
color print run statement group's first
line.

checks with printers operating in nor-
mal speed mode for graphics. Printing
times do not include paper and ribbon
handling operations.
Program Description
The card program has three func-
Direct coding allows FOR. ..TO
loops and GOSUB routines to re-
peat identical parts of card art. These
functions reduce coding and memory
requirements. Since direct coding also
eliminates the normally used and rela-
tively slow REA D...PRINTdala loops,
it speeds up graphics printouts.
Gemini-lOX printing time per card is
about 9 3 /4 minutes at 4800 Baud. An
Epson FX-80 prints cards about five
percent faster at the same Baud rate.
MX-80 print time per card isabout 1 3 '/2

tional sections. A top section displays
run instructions and in-progress mes-
sages, initializes the printer for each
print run, and has common GOSUB
routines usable in all color print runs.
A middle section contains dot gra-
phics printing code sequence groups for
all color print runs. Each group's first
statement line specifies the color used,
defines local string codes for the run,
and starts a card counter.
A bottom section defines global string
codes for dot graphics. It also displays
an introduction, starting prompts, and
instructions for the first color print run.
Remark Line l identifies the program
and specifies the equipment needed to
print continuous cards. Line 2 clears the
screen and additional string space, iden-
tifies the starting print color, then jumps
to title and coding routines.
Lines 9000-9020 display the program
introduction and a printer power on/ off
caution. The display persists while Lines
9060-9200 define the string codes for
dot-column patterns, frequently used
pattern groups, and printer mode con-
trol commands. Line 9200 also displays
a "Press space bar to start" prompt,
then EXEC44539 waits for the user's
key press.
Line 9210 asks for the number of
cards wanted (NC) then tells how many
fanfold sheets are needed. Line 9220
asks for the card's signature name ( NCS)
and calculates a tab value (NX) for
printing the signature flush-right below
each card's multicolored greeting text.
Line 9230 asks for a card-printing credit
name (PCS). Line 9240 calculates a tab
value (CX) for centering the credit on
each card's back page.
Lines 9250 and 9260 display instruc-
tions to insert, align, and index mark
the fanfold paper strip. Line 9260 also
displays a start prompt, then sends con-
trol to the first color print run's state-
ment group, starting at Line 1000.
Line numbering within the color print
run statement groups is very irregu-
lar for good reasons. The first digit iden-
tifies the print run. The second and third
digits roughly identify sketch layout
sheet and color copy print lines to sim-
plify program debugging. The fourth
digit allows several statement lines of
code for very long or detailed dot-
graphics print lines. Also, where practi-
cal. I use multiple statement lines to
conserve memory — each line number
used takes five bytes.
Multiple statement Line 1000, for
example, defines the print run color
(CYS), then loops through Lines 70 and
75. Line 70 waits for a start-print key
press. Line 75 clears the screen, displays
a "Now local coding and printing red
color" message, sets the printer for dot-
graphics line spacing (L Y$), and returns
control to the calling statement.
Now Line 1000 defines three local
string codes (RS.OS. and QS) for reuse
during the red print run. RS defines a
six-column pattern for the card cover's
border. OS is a complete graphics seg-
ment that prints one RS border pattern.
The line's FOR.. .TO loop counts the
cards being printed. A loop through
Line 3 displays a card in progress
number after each increment of the card
counter.
GOSUBI9 prints the inverted card
art's upper border. T—18 specifies a
number of print lines to receive left and
right border RS patterns; GOSUB21
prints them. GOSUB23 prints a left
border pattern on the 20th print line,
then Line 1000's PRINTHM graphics
segment colors the small deer's lower
mouth area red, and adds a right border
pattern. Another GOSUB23 prints the
21st line's left border.
Lines 1210-1280 similarly print border
patterns and deer head red details down
through the 30th print line. From that
point, T=7 and GOSUB21 print seven
more pairs of border patterns. Lines
1370-1440 print more border patterns,
the card's title in three-line high letters,
and the lower border.
T=24 and GOSUB10 in Line 1440
advance the paper 24 lines for printing
the emphasized, double- width
CHRISTMAS in the card sheet's lower-
right quarter. Code ECS form feeds the
paper to the next sheet's start point.
Finally, NEXTCN increments the card
counter, starting another red printing
sequence within Line 1000.
When the last card (sheet) is printed.
Line 1 440 loops through 90 and 9 1 , end-
ing the red color print run. Line 90's
ARS"E" codes disable the printer's
paper-out sensor, then ECS does an
extra form feed. Disabling the paper-
out sensor lets the printer move the fan-
fold paper strip's tail end clear of the
print head. Line 91 moves the print head
for easier ribbon change.
Control drops to Line 2000 for the
next (brown) print run. A loop through
Lines 35-75 displays new instructions
and reinitializes the printer for dot
graphics. Line 2000 then defines four
local string codes, starts a card counter,
and does four line feeds. Lines 2050-
2310 print the card's brown details.
Lines 3000. 4000. and 6000 similarly
start blue, green, and black color print
runs.
Credit print run starting at Line 7000
alters instructions to include paper strip
reversal and start point adjustment.
Line 7000 also resets the printer's line
spacing to %", then line feeds the paper
56 times. Line 7020 starts a card counter
and sets the printer to subscript charac-
ter mode. Line 7030 prints the card-
printing credit lines, form feeds, and
increments the card counter for each
card. Finally, Line 8990 displays a
"Cards Done" message when the last
greeting card's credit lines are printed.
Many color print run statements call
GOSUB routines to print specified
quantities of column patterns or identi-
cal dot graphics segments. Line 20's
routine, for example, overprints the
large tree's sparse brown and blue tex-
ture patterns with T-specified quantities

Hints and Precautions
Type the program exactly as shown in
the listing. Every character and space is
Unfortunately, the printer is not as
forgiving or helpful in the dot graphics
mode: it insists that you specify and
provide exact quantities of dot-column
codes for each graphics segment. Any
code error or difference between code
quantity specified and supplied disrupts
the printed graphics line. And. you
don't get any clues as to where the evil
error lurks.
Be especially accurate when typing
program line characters and spaces
shown within quotation marks. Each
December 1984 THE RAINBOW 133
letter, number and symbol represents
an equivalent ASCII value dot-column
pattern. Each space represents an ASCII
32 blank dot column. Only an exact
duplicate of the listed card program
ensures faultless program execution and
card printout.
Note: If your keyed-in program fails
to print cards correctly. LLIST the
faulty color print run's statement lines
to your printer and carefully compare
them with the published listing. If all
statement lines match exactly, recheck
coding Lines 9060-9200. When all else
fails, send me a printout of the faulty
color print run statements, a copy of
your bad card printout, and the model
designation of printer used. Include an
adequate SASE for return of your ma-
terial and an answer.
Program Line 91 moves the print
head to the right seven spaces for easier
ribbon change on tractor feed Epson
printers. For MX-80F/T and Gemini
printer use, add SCS between Line 91 's
PRINTffM, command and spacing code
S7S. The SCSS7S combination centers
the print head between the two plastic
rollers on the printer's paper press or
scale bar.
Configure your printer for an auto-
matic line feed with each carriage return.
Do this by setting your printer's line

Displayed instructions may appear
long before a print run ends if your print-
er has a serial interface with a large
character buffer. In such a case, allow
enough time for print runs before re-
sponding to instructions. Play it safe by
adding code A 7$ after PRINT* M, iii
Line 90. A 7$ sounds a beep tone when a
print run ends. You must set an MX
printer's internal DIP switch SWI-6 to

ribbons are available from F.F.

spool Gemini ribbons are inked for dot
matrix printer use. Write orcall him for
details. You may also find some type-
writer color ribbons locally that can be
rewound on Gemini ribbon spools. But.
be careful! Several of the typewriter
color ribbons 1 tried were over-inked or
waxy and quickly gummed up my Gem-
ini's print head.
Check your fanlold paper. If it is laser
perforated, verify that its horizontal
perforations will survive at least six
back and forth folds without splitting.
Do not use paper that fails this test.
Clean the print head before each card
printing session, or dark ink deposits
may contaminate your red ribbon. Fold
a piece of smooth, firm papertowel into
three layers and crease into a U shape.
With ribbon removed, slip the paper
towel's U-creased area between the print
head and its ribbon guide. Wait 10
seconds and remove towel. Repeat this
action with the unused part of towel
until it comes out clean. Put a drop of
isopropyl alcohol on the towel's U crease
to dissolve thick or dried ink deposits.
Do not use a short tabletop printer
stand when printing continuous cards.
Paper movement around the very short
turns creates uneven drag that may
cause irregular line spacing. Position
your printer on a table or stand so that
blank paper feeds straight upward from
the floor. The extra hanging sheets'
weight helps keep the paper slightly taut
in the print head area, especially on
Gemini and Epson friction/ tractor feed

primers. Also, relieve the fanfold creases'
permanent set by reverse folding the
paper strip lor card printing.
Do not plug your computer and print-
er power cords into the same circuit.
Power surges caused by printer on/ off
switching during program operation may
glitch the program or halt the CoCo.
Use a reliable power surge protector on
your computer's power cord, or plug
your computer and printer cords into
different circuits.
Producing Cards
Color greeting cards require a separ-
ate print run for each color used. You'll
need a continuous fanfold paper strip
with a sheet for every card plus leading
and trailing blank sheets. You must
position the paper horizontally and ver-
tically to accommodate the card's cover
art, greetings text, and credit lines with
enough blank margin for trimming after
the sheets are folded. The fanfold paper
strip's start point, established for the
first print run. must be exactly the same
for the remaining print runs. Use a 20-
pound white bond paper.
Before attempting to load and run the
card program, adjust your printer's trac-
tor feed mechanisms horizontally as
specified below.
On an FX-90 printer, insert a blank
fanfold sheet, then move both tractor
Iced mechanisms fully rightward. Adjust
either or both mechanisms to center
their drive pins within the paper's pin
feed holes. Lock both mechanisms.
On other Epson and on Gemini print-
ers, adjust tractor feed mechanisms to
position the paper horizontally as shown
in Figure 2. Lock both feed mechanisms
after adjustment.
Paper edge and fixed index marks
provide a fairly accurate means for
repositioning the paper strip's start point
between print runs. When instructed
during program execution, establish the
index marks as follows:
Feed the paper strip into printer and
engage the paper's pinfeed holes with
pins of both tractor feed mechanisms.
Using the printer's paper feed knob,
advance the paper to position its first
fanfold crease '/*" below the ribbon
guide's top edge (Figure 2).
On FX-80 printer, attach a short
strip of white sticky-back label to
right feed mechanism's sloping front
area just outboard of the gray drive
sprocket's right edge. On other printers,
attach short label strip to the outer rear
flat surface area on top of the right Iced
mechanism. Position the label strip next
to or slightly under the paper's right-
hand edge.
Using a fine-point pencil, draw a
short straight line across the paper's
edge and the fixed label strip. The two
resulting marks are used as paper repo-
sitioning indexes for subsequent color
print runs.
Load and start the card program.
Displayed instructions tell you what to
do in a specific order. The last instruc-
tion tells you to press the 'P' key to start
the first color print run. Printing con-
tinues until the last card's red details are
done. New instructions tell you to turn
printer off, restart paper strip, insert
slipsheet. change ribbon, remove slip-
sheet, align index mark, turn printer on,
and start the next print run. Follow all
instructions exactly and in the given
order.
When instructed, re-insert the fanfold
paper strip's start end into printer. Ad-
vance the paper until its index mark is
within Va" of the fixed index mark. Stop
at that point, grasp input part of paper
at both edges (just behind the paper
separator), and pull it straight back
slightly. Now. carefully and slowly ad-
vance the paper to exactly align its
index mark with the fixed index mark.
If you pass the fixed mark even a little

Printer Art!
Turn your printer into an artist with this delightful
package of four 16K Extended Basic programs! The
pictures on this page are just a sample of the fun in
store for you, your family or classroom. Printer
Artist introduces you to the craft of " Artyping," the
creation of pictures using typewritten characters.
The package includes a dozen ready-to-run draw-
ings of animals, people, patriotic scenes, famous
Americans and more. There are instructions for an
additional 40 pictures you can create with two dif-
ferent utility programs that will allow you to set up
a file of printer art and save it to tape or disk. Our
manual includes a complete discussion of printer
art programming techniques. It's a good way to
learn typing skills, too. Works with any 80-column
printer. Only $24.95 on tape, $27.95 on disk. Add
$1.50 for postage and handling. See our ad on the
following page for other fine programs from Feder-
al Hill Software.

bit. backfeed the paper about Vi" (don't
forget the slight backward pull) and try
aligning the index marks again.
The slipsheet requested in the instruc-
tions can be any piece of thin paper
about lour inches square. Inserted be-
tween the fanfold paper and print head's
ribbon guide, the slipsheet prevents ac-
cidental color smudging during ribbon
change.
Credit run instructions tell you to
reverse the fanfold paper strip and insert
its tail end into the printer. Feed the
paper forward until its first fanfold
crease aligns with the top edge of the
printhead's ribbon guide. Index marks
aren't needed.
When the credit print run ends, re-
move the paper strip, and separate the
sheets at their horizontal perforations.
Referring to Figure 1, fold a printed
card sheet horizontally about '/n." above
the card art's top border.
Next, make a vertical fold within '/| 6 "
of the cover art's left-hand border.
Place the folded card face-up on a
metal or glass surface and, using a metal
straightedge and single-edge razor blade
or hobby knife, trim the card within '/ii."
ol its right-hand border. Similarly trim
the card about '/is" below its bottom
border. Cards folded and trimmed this
way fit into standard 4!/i" by 5*/»" enve-
lopes available at many office supply
stores and print shops.
Avoid unpleasant surprises. Famil-
iarize yourself with card printing by first
trying one card, using three fanfold
sheets and a worn or old ribbon.

Color Computer, written entirely in
Machine Language. "View" oriented
means that the pilot may determine his or
her position by actually viewing the sur-
rounding landmarks as opposed to using
instruments which sense navigational
references. This is a major departure from
"instrument only" simulations which can
be achieved through BASIC programs.
Most instrument maneuvers and pro-
cedures may be practiced. The craft is a
light-weight, single-engine airplane with
low wings. A nose wheel which is both
steerable and retractable is also modeled.
Some aerobatics are possible including
sustained inverted flight, aileron rolls,
spins and stalls.

COLOR BASIC COMPILER!
II you have ever written a BASIC program only to find that it runs
too slow to provide any action and haven't had the courage to learn
assembler, then the Color Compiler" s the answer. It lets you write
your program in easy BASIC and then converts it into fast machine
language After you run your compiled program, you may find it
necessary to add some delays because the Color Compiler* will
make your program run an average of 40 times faster
The Color Compiler ' features a total ol 55 commands and
functions Mosl of these are a subset of Extended Color BASIC The

REAL TALKER'
HARDWARE Voice Synthesizer
NEW from
COLORWARE..
only... $59.95
THINKING OF BUYING A
COCO VOICE SYNTHESIZER?
READ THIS....
Making your computer talk couldn't be any easier!
'Real Talker' is a full featured, ready to use, HARDWARE
voice synthesizer system in a cartridge pak. It uses the
Votrax SC-01 phoneme synthesizer chip to produce a
clear, crisp voice.
FREE TEXT-TO-SPEECH
Included free with 'Real Talker' is Colorware's
remarkable Text-to-Speech program. This is a truly
powerful machine language utility. What it does is
automatically convert plain English to speech. And it has
an unlimited vocabulary! For example, use it in the direct
mode: Type in a sentence or a paragraph, even mix in
numbers, dollar signs, etc., then press enter. The text is
spoken. At the same time a phoneme string is generated
which can be saved to cassette or disk, modified or used
in a Basic program.
We originally planned to sell this major piece of
programming for about $40.00 but decided it was so
useful that no 'Real Talker' user should be without it.
Besides, it really shows off the capability of 'Real Talker'.
Also included with 'Real Talker' is our unique Phoneme
Editor program. It allows you to explore and create
artificial speech at the phoneme level. Phenomes are the
fundimental sounds or building blocks of word
pronunciation. There are 64 different phenomes, as well
as 4 inflection levels at your disposal. Creating and
modifying speech at the phenome level is both fascinating
and educational. The Phenome Editor may also be used to
customize the pronunciation of speech produced by the
Text-to-Speech program.
~«^o
You don't have to use any of our utility programs
though. If you write your own Basic Programs, you will
find the pocket sized Votrax Dictionary (included free) is
all you need to make your own Basic programs talk. This
dictionary gives you quick access to the phenome
sequences used to create approximately 1 400 of the most
used words in the English language.
How about compatibility? 'Real Talker' is compatible
with any 16K, 32K, 64K, Extended or non-extended Color
Computer. It works with any cassette or disk based
system, with or without the Radio Shack Multi-slot
expander. No other synthesizer under $100 can make this
claim. Most other CoCo voice synthesizers require an
expensive Multi-slot expander in order to work with the
disk system. 'Real Talker' requires only an inexpensive Y-
adapter. This is an important consideration if you plan on
adding a disk or have one already.
'Real Talker' comes completely assembled, tested and
ready to use. It is powered by the CoCo and talks through
your T.V. speaker so there is nothing else to add. Price
includes Text-to-Speech and other programs on cassette
(may be transferred to disk), User Manual and Votrax
Dictionary. ONLY $59.95
'Y-BRANCHINC CABLE' For disk systems. This 40-pin, 3
connector cable allows 'Real Talker' to be used with any
disk system $29.95
YOU DECIDE....

not delighted with your 'Real Talker' system, simply
return it within 30 days for a prompt, courteous refund.

Canadians !
Seasons Greetings to all Canadian
Color Computer Owners and Dealers
We wish to thank all of our Retail and Wholesale
Customers for their support during the past year. It
has been a year of growth for us and we have
greatly improved our production and publishing
facilities. We now employ full-time artists and
programmers to assist Canadians with their software
selections and the publishing of Canadian programs.

EXPANDING BASIC

Part VI
By Colin J. Stearman

If you think CoCo is without
parallel, this month we cook up
something to prove you right
and wrong!
154
Ilove my printer. It prints quickly, it
prints letter quality, it draws pic-
tures, I can send it my own charac-
ter fonts . . . but the darn thing has a
parallel port and CoCo has a serial prin-
ter output. Sure I can buy a serial inter-
face for it but it's over 25 percent of the
cost of the printer alone, and I hate to
waste money. The only solution is to
design a parallel port for CoCo.
The actual design is easy, but I wanted
the software to fully integrate the port
into basic, allowing me to direct printer
output to either the parallel port or the
existing serial port; and for good mea-
sure I wanted the BASIC to allow easy
adjustment of the Baud rate on the
serial port.
To achieve all this meant adding
initialization code for the parallel port
hardware, trapping output destined to
go to the serial port and redirecting it to
the desired printer port. This month's
assembly language listing does all that
as well as adding three new BASIC com-
mands. If you do not need this parallel
port and are thinking of turning to the
next article, two of the new commands
apply to the existing serial port also, so
maybe you might want to stick around.
But before we get to the software, let's
get the hardware built. If you didn't
have trouble with the EPROM pro-
grammer, this project will be a snap.
Adding The Parallel Port
The object of the construction is to
mount a new 682 1 PI A (peripheral
interface adapter) inside the computer,
without making irreversible modifica-
tions to the circuit board. I did this by
"piggybacking" the new PIA onto U4.
The photos of my unit should give you
an overall idea of the look of the fin-
ished unit.
U4 is an existing PIA used to drive
the D/A converter and control the
VDG chip. Please note that these modi-
fications refer to the REV E-style mother-
board. If you have a later model, your
PIA may not be labeled U4 and will
have to be identified by the function it
performs.
To construct the unit, first gather the
following components together:
l)682l PIA Peripheral Interface
Adapter
2) Breadboard PCB Radio Shack
#276-158
THE RAINBOW December 1984
3) SN7404 Hex Inverter Radio Shack
#276-1802
4) 40 Pin IC socket, wire-wrap type
5) Thin hook up wire
6) Flat ribbon cable, 36 conductor
wide
7) Centronics-type female plug, rib-
bon mounting
Items 1 , 4, 6 and 7 are not carried by
Radio Shack but are available via mail
order from Active Electronics, West-
boro, Mass. and other sources. The IC
socket must be the wire-wrap type.
To assemble the parts, first remove
the cover from CoCo and also the RF
shield lid inside. Locate U4 (REV E
board #), the 6821 on the right as you
face CoCo. Gently pry the IC out of its
socket, using a small screwdriver or IC
puller. Be careful not to damage the
pins. Put CoCo to one side as we will
now construct the "piggyback" board
assembly.
Mount the 40-pin socket to the PCB
(printed circuit board, item 3) anywhere
convenient, but leave room for the
SN7404 near pin 24. Solder all pins on
the socket to the PCB, but do not cut off
the excess.
Take the new 6821 and gently bend
pin 24 outward a little so that when the
IC is put into the socket, this pin will not
enter it. Put the IC in the socket and
press it home.
Mount the SN7404 alongside the 682 1
near pin 24. Solder all pins to the PCB.
Using the hookup wire, connect pins I,
3, 5, 7, 9 and 1 1 together and also to pin
20 of the 40-pin socket. Connect pin 14
to pin I on the 40-pin socket. Connect
pin 1 3 to pin 24 of the 682 1 . This is the
bent pin not inserted into the socket.
Also connect this pin to a length of wire
about nine inches long. The other end
will be connected later. Connect pin 12
to the 40-pin socket pin 24.
Turn the PCB upside down and cut
off the wire-wrap pins from pins 2
through 19 only. Cut them as close as
possible to the PCB. The next task is to
mount the assembly on top of the 6821
removed from U4.
Locate the 6821 removed earlier from
CoCo and carefully bend pin 24 so it
points vertically upward. Position the
assembly on top of this IC to test for fit.
It may be necessary to splay the wire-
wrap pins out a little. In order for the
finished assembly to fit under the RF
shield lid, the remaining wire-wrap pins
must be trimmed as short as possible.
Gauge how much you can cut from each
pin and then trim all to this height.
Now solder the assembly to the 682 1 ,
soldering each wire-wrap pin to its
respective pin on U4. You should be
connecting to U4 pins I, 20, and 21
through 40. The wire-wrap pin 24 will
connect to the upturned pin 24 on U4.
This pin will not connect to the socket
when U4 is returned to the CoCo mother-
board. When soldering the assembly to
the back of U4, minimize the amount of
solder used so that the IC will still fit
into its socket. Also position the solder
joint high on the pins so that the lower
part will still fit the socket.
Finally, the ribbon cable must be at-
tached to the assembly. Consult your
printer manual and Figure 1. The best
approach is to fit the Centronics socket
to the ribbon cable to aid in identifying
the wire numbers. Most sockets have
the numbers molded into them. On the

Connect the wires to the pins as indi-
cated in Figure I. Wire 14 should be
connected to any V point on the assem-
bly. Finally trim all the excess PCB
from the assembly to minimize its size.
Now mount the finished assembly
into CoCo. Press the lower 1C gently
but firmly into the U4 socket. All pins of
the lower 6821 must enter the socket,
except for pin 24 which was bent up-
wards. It's not easy to see that this
happens, so inspect the results carefully.
The assembly should be firm and quite
rigid when installed.
The wire still left unattached must be
soldered to the main computer board
near the 6809. Cut this wire to a suitable
length and attach to the solder point, as
indicated in Figure 2. Use a light solder
tack to minimize the possibility of dam-
age to the board. This wire picks up
address Line 2 to allow the software to
distinguish between the two PIAs.
The ribbon cable will head toward the
left as you face CoCo. Take the RF
shield lid and bend the fingers where the
cable is, so the lid can be replaced with-
out pinching the wire. If the assembly is
too high to allow the lid to be replaced,
either leave it off entirely, or extend the
height of the RF shield using some
shielding metal from an old TV.
156 THE RAINBOW December 1984
The ribbon cable can be routed out of
the computer by doubling it back on
itself and running it under the main cir-
cuit board. A notch cut in the lower
plastic shell underneath the serial and
cassette ports will allow the cable to
leave the case.
This completes the hardware construc-
tion. We now move on to this month's
software additions to the Disk basic
patch.
The New BASIC Commands
This month we add three new com-
mands, all associated with the printer
port. Two apply even if you do not
intend building the parallel port, so
stick with us.
PARALLEL
Issuing the basic command PAR-
ALLEL, either directly from the key-
board, or within a program will result in
all data destined for the printer being
routed out of the new parallel port. In
other words, all PRINTtt-2 statements
will output through the parallel port.
The code to drive the parallel pqrt is
conditional assembled based upon whe-
ther a variable called PARFNT'a defined
or not. Review the paragraph in Sep-
tember's issue for more details on how
to include or exclude the code for the
parallel port, as desired.
BAUD
This command applies whether or
not you have the parallel port. Either
way, it establishes the Baud rate of the
serial port. If you have the parallel port,
it also activates the serial port so that all
PR/NTtt-2 commands direct output
through the standard serial port. The
original serial driver code in the Color
BASIC ROM is still used for the serial
port.
The syntax for this command is:
BAUD(n)
where n = 300, 600, 1 200. 2400, 4800 or
9600.
If you have the parallel port, then
CoCo starts up with this activated. If
you do not, then the serial port is acti-
vated and set at 600 Baud.
LDIR
A simple but useful command which
does a normal directory but directs it to
the currently active printer port. The
directory contains the creation date
enhancement, but, of course, does not
pause after each 16 lines, as when direct-
ed to the screen.
Adding This Month's Code
As last month, use your editor to pull
in the source code built up so far. Delete
the lines identified with reference num-
bers 20, 2 1 , 22. and 29. Read and follow
the notes at reference Lines 6, 7, 8, 10
and 1 1 regarding including or excluding
the parallel port code.
Go to the end of the listing and delete
all the remaining lines from and includ-
ing ZZLAST EQU *-/. Then add the
assembly text in Listing 1. When all is
set, re-assemble the resulting file and
test as you have in previous months.
To test the parallel port, connect it to
a printerand try LLlSTing a BASIC pro-
gram or run some other program which
has printer output. If it does not work,
but the computer works otherwise, dou-
ble check your wiring on the new PIA,
especially around the ribbon cable con-
nection point. It's very easy to miscount
the wires.
A Final Point
All BASIC programs will have no
trouble sending output to the parallel
port. However, you may have trouble
with some machine language programs.
If they use the serial port in the Color
BASIC ROM anddonot"mess"withthe
hooks in RAM. the port should work
alright. If the program has Baud rate
control, set it to 1 10 or 120 and this will
activate the parallel port; 300 or higher
will activate the serial port.
If you have FH L FLEX then you can
use the parallel port driver routine des-
cribed in the FLEX manual. The reason
that the BUSY line goes to both pins 9
and 19 on the new PI A is specifically to
accommodate the approach these rou-
tines use to detect the printer busy con-
dition. From a programmer's point of
view, the PIA is addressed as follows:
FF24 Bit - 6 unused
Bit 7 printer busy line
FF25 Control port for above (set
to $4)
FF26 Bit - Parallel

This should provide the information
you need to incorporate the parallel
port into FLEX. Drop me a line if you
have trouble.
Coming Attractions
One of the glaring omissions from
basic is its ability to trap and deal with
system errors in a graceful way. We will
add this trapping, along with fully spelled
out error messages, both on the screen
as well as available in a string variable;
plus variables identifying the type of
error and the line number it occurred.
If you would like the entire DOS-
PA TCH program source, along with
binary files with and without the paral-
lel port driver for DECB 1 .0 and DECB
1.1. just send me a disk (no cassettes
please) along with $6 and a stamped,
addressed disk mailer. 1 will load the
disk and return it to you promptly.

Radio Shack released a Color
Computer with 4K, expandable
to I6K. That was it; 16K was to
be the maximum amount of memory
that could be obtained from it. However
a rather intelligent gentleman wrote an
article in the March 1981 BYTE maga-
zine, telling how to piggyback 1 6K chips
and fool the SAM and CPU into seeing
32K.
Rumors flew fast and furious about a
32K memory kit from Radio Shack. It
involved the use of partially bad 64K
chips. Now the minds at Frank Hogg
Laboratories went to work. Using an
extra gate already available on the board,
they could toggle the upper bank of the
64K chips in and out, thus, making the
current 64K Color Computer we have
today. Everyone went to work to develop
a I28K modification, but the same
stumbling block kept getting in the way;
the ROM version of BASIC will only
support 32K. With prices dropping on
computers faster then pig bellies on
Wall Street, most research went the way
of the horse. Sure, there are a couple of
I28K modifications currently available,
however the hows and whys are being
kept guarded secrets, making software
support almost impossible.
(Dennis Lewandowski. one of the early
authors active with the Color Compu-
ter, specializes in machine language
programming. He and his wife. Rose,
founded DSL Computer Products.)
Now a little background on this I28K
modification. The main objectives are
basically common sense. The modifica-
tion must be usable by BASIC, and rela-
tively inexpensive to upgrade the cur-
rent CoCo. It also has to like FLEX, and
OS-9. For these objectives to be reached
we chose to use two sets of 64K chips.
There are six other chips involved in the
modification, which take care of select-
ing the banks. Actually five of the chips
take care of the bank selection, but due
to timing considerations, the sixth chip
makes certain that the computer oper-
ates with RAM chips of all speeds. The
method was limited to bank selection
By Dennis Lewandowski
since the CPU can only address 64K at
any one given time. We chose to ex-
change the lower banks of 32K, address
between zero and 32767 (0000-7FFF).
Now with three lower banks of RAM,
BASIC can have three programs resident
in memory. Also there is another 32K
bank of RAM, addresses 32768 to 65535
(8000-FFFF), where a control program
can be placed to operate the lower three
banks, similar to I28K operation of an
Apple II. Realistically speaking, with
ROM included, there is a total of I60K
available. Refer to Figure I for a block
diagram of how the 32K pages are
configured.

How To Do It
The simplest way of inserting mem-
ory, since there are only eight RAM
sockets, is to piggyback the chips. There
are data lines running through the
74LS244 (Ul9), that exist only at that
chip. To place the additional RAM
anywhere else would require the remov-
al of the 74LS244 and installing a series
of jumpers from its position. The draw-
back of this is since late version "E"
boards, the 74LS244 has been soldered
onto the board. Also the more wire that
runs around inside the computer, the
more noise (RF) the computer will
generate. By piggybacking the 64K chips,
these problems disappear. Most of the
signals required to operate more mem-
ory will come from the SAM chip; to do
this the SAM is elevated by means of a
wire wrap socket. The additional chips
are then placed on a board attached to
that socket. Depending on your own
level of soldering ability, there are a
couple of ways to proceed. Using the
suggested board layout (Figure 2), cut a
sheet of perf board to dimension. Then
follow the wiring diagram (Figure 3),
and hand wire the board. The parts
necessary to make 64K CoCo into a
128K CoCoareas follows:

One important item is that pin 1 1 of
the SAM chip does not go through to
the original socket as all the other pins
do. It should be cut off right below its
connection to pin 4 of the 74LS32.
If you prefer the board with the six
chips soldered and tested, it is available
from DSL Computer Products for
$34.95. If you want to just plug in and
go, the complete mod including an addi-
tional 64K of RAM is $99. The installa-
tion of the complete mod is solderless.
How To Use It
Once the I28K modification is done,
what can you do with it? When you
power up the computer everything
should be the same as normal including
the familiar answer to the ?MEM ques-
tion. So how do you have 128K?Typein
the command POKE &HFFAE.0 and
press ENTER. Now if you see garbage on
the screen this is normal, press Reset,
and the computer powers up again. If
you don't have a disk system the com-
puter will reset automatically, usually.
You are now in bank zero, page zero of
RAM. This is the normal bank in which
a 64K Color Computer will power up.
To enter the upper bank of 64K type
POKE& HFFA C.0.POKE& HFFA F,0.
Again, if you see garbage just press
Reset. You are now in bank one, page
zero. (One way to be sure you are switch-
ing banks is that the screen will change
with the bank. If the poke has no effect
you may have a wiring problem.) Finally,
type POKE&HFFAD.0. This is bank
one, page one. Now all three lower
pages of I28K mod have been initialized.
Referring to Figure 1 again, the nor-
mal memory map has not been changed,
but rather modified. Two 32K pages
have been added along side the present
32K. page used by BASIC. All current
software will run as it normally does.
The only way a different bank can be
accessed is by poking (writing) to a
memory location between 65452 and
65455. The value poked into that address
can be zero to 255. By switching banks,
three programs can reside in the com-
puter at the same time. The CPU can
only run one program at a time, unless
another operating system is controlling
it, such as FLEX or OS-9. However, all
three programs can be run in such a way
that it will seem that they are runningall
the time. There is one consideration
using BASIC; that is the location of the
Slack Pointer. If one of the programs
clears space for strings or arrays, the
Stack Pointer would be adjusted. Then
when that bank is switched out the
Stack Pointer would be pointing to
nowhere. The results could cause the
computer to lock up. For this reason
there is a program listing included called
STA KSTA T. This will initalize all three
lower banks, transfer ROM to the upper
bank of RAM, and add a new command
to BASIC. By entering the command
PAGE x. where x isO, I. or 2, that page
will be selected and the correct stack
value will be placed into the Stack Point-
er. Please note that STA KSTA 7" can be
used freely with any 128K software that
you develop. However, if you wish to
send it to a magazine to have it pub-
lished, remember where you saw it first!

DRACONIAN
You brace yourself as your ship materializes In the enemy
sector. Your engine roars to lite, and you consult the long-
range scanner for the position of the nearest enemy base. As
you head for the base, blasting asteroids and space-mines in
your path, you suddenly notice a monstrous space-dragon
looming before you. Reacting quickly, you dodge his deadly
fire-breath and blast him out of existence.
Finally, the enemy base comes into view. Avoiding the
enemy fire, you destroy the gun turrets one by one with your
rapid-fire torpedoes. Then, with the explosions still echoing
around you, you rescue the astronaut who was being held
prisoner by the enemy. Your mission is far from over, however,
as there are more bases to destroy and more astronauts to
rescue before the sector will be secured. And all must be done
quickly; if you are too slow, the invincible DRACONIAN will
surely seek you out as its next victim.
This Is it — the single most impressive, awe-inspiring arcade
game you can buy for your Color Computer. High-resolution
graphics, awesome sound effects, four-voice music, and quali-
ty you have to see to believe! Experience the realism of

MATH DUEL
MATH DUEL is a challenging mathematics game that pits you againsl the
computer it a game of wits. You must use all of your knowledge of factors,
multiples and prime numbers to develop a strategy that allows you to gather
more numbers and thus more points that than the computer.
The game is deceptively simple. You select the size of the playing field
that Is composed of from 8 to 100 numbers. You must then choose numbers
that will give you the maximum number of points and the computer the least
number of points. There are only 6 rules.
1 . Any number that you chose must have at least one factor still on the
playing field.
2. You receive points equal to the lace value of the number that you chose.
3. The computer receives points equal to the face value of all of the remaining
factors of the number that you chose.
4. All of the numbers that were awarded to you or to the computer are
removed from the field.
5. The game continues until there are no numbers with factors remaining.
6. At the end the computer receives points equal to the value of all of the
remaining numbers.

The Tale Of The Tape
By Ed Ellers
Rainbow Technical Writer
• / was wondering if there are any differ-
ences between tapes or tape inputs on the
original CoCo and those on the CoCo 2?
J. V. Hoell
Kitchener, Ontario
This has come into question in recent
months, with reports of tapes that loaded
fine on the older models but wouldn't work
on the CoCo 2. There were some drastic
changes made to the CoCo 2 (and even more
on the way), but since 1 haven't seen the
service manual I don't know what if any-
thing has been done to the cassette input and
output circuitry. Something 1 do know is
that both CoCo models are designed to work
primarily with Radio Shack's tape recorders
(CTR-80. CCR-81 and CCR-82). These re-
corders were reworked to provide reliable
operation on the old TRS-80 Model I, and
have slightly different audio characteristics
from their twins in the regular cassette
recorder line. The CoCo is somewhat more
forgiving, but different tape recorders (even
from Radio Shack) may still give uneven
results. Another critical factor is the volume
control setting; on the Radio Shack com-
puter recorders it seems to work best at a
setting of three.
Where's The RAM?
• / have a 16 K Extended computer, and I
recently tried to type in a rather long listing.
I got an OM error, and when I turned the
CoCo off and hack on. and entered PRINT
MEM. to my surprise it showed 8487 bytes
of memory. I examined several locations in
memory from zero to 4FFF which indicate
that the missing memory does exist, but then
I'm a novice at this.
Pal McKenzie
Manila. NY
(Ed Ellers. a rainbow and pcm staff
member, is a self-confessed electronics
fanatic whose other interests include
science fiction.)
It's there all right, but a lot of it is being
used. Typing PRINT MEM will give you the
size of the RAM area available for your
program after variable space. Hi-Res screen
pages and the area that basic uses to keep
track of what's going on. PC LEA Ring more
graphics pages will give you less room: con-
versely, using fewer than four pages will free
up some space, but you then lose the use of
the higher graphics modes. If you don't have
a disk system hooked up, a POKE 25,
6:NEW command will drop all the graphics
pages (for some reason, you can't just
PC LEAR 0) and give the same amount of
useful RAM space (14631 bytes in a I6K
machine) that you would have if you had
only Color basic.
More MC-10
• On Page 1 90 of the No vember 1 984 issue,
you mention that the MC-10 will only oper-
ate at 600 Baud. In fact, the MC-10 will run
at other Baud rates by POKEing in a new
value (the same way as on the CoCo). Here s

The Case Of The Cases
• Just a quick comment on your reply to
Alexandre Maggioni (October 1984) in re-
gard to identification of the circuit board
type. My experience has been that the cen-
tered nameplate is not a dead certain way to
identify an F' board CoCo. I have seen
many late model '£" board units with cen-
tered nameplates. This might save some
poor fellow a lot of headaches.
Glenn Gernert
Moscow. ID
Thanks for the tip; I've also heard that
some of the earlier 'F' board machines had
the old tops. Obviously, since you need to
take the top off the machine to do the
upgrade, you will find which board you
have; the 'C'.'D'and 'E'versionshavea large
RF shield with a lid that comes off easily
(much like a UHF TV tuner, if you've ever
seen one) while the 'F' board uses a much
smaller shield with lugs under the board that
have to be bent outward.
While on the subject of upgrades. I'm told
that the very latest CoCo 2 (which is made in
Korea) has three of its RAM chips in one
row on the board and the other five in
another. Instead of W I, the two pads (which
are now fairly big and easy to solder across)
are outlined by a box marked "64K."
Entering The Dragon's Lair
• Is there any way I can gel CoCo pro-
grams on cassette to load and run on my
Dragon 32 without hours of editing when
the programs are supposedly capable of
running in my machine?
Geoff Whitham
Mackay. Australia
In the case of basic programs, all you
need to do is save them in ASCII (use
CSA VE "filename" ,A). Most of the time
(when the program is straightforward and
doesn't use cute programming tricks) this
will work, and on the Dragon 64 (same as the
U.S. model) you can usually use CoCo pro-
grams in the 64K mode as well. ^_

Game module 1 — House to House. Ark Royal's squad level WWII
inlantry combat game.
They said it couldn't be done — a SQUAD LEVEL wargame on a com-
puter — but we've done it. The Line of Sight problem is licked — and the
machine language routines really speed things up.
Game Module »1 comes with House to House map and 10+ scenerios
involving infantry combat in Aachen, Caen, Arnheim, Stalingrad and
other famous WWII city battlegrounds. Combat units include rifle
squads, mortar teams, machine gun crews, engineers, and more
(depending on the scenerio chosen), leaders, vehicles and other
weaponry of WWII. Unique design allows incorporation of future
expansion modules.
Choose campaign play and put yourself on the battlefield, Corporal
Smith or Jones; collect points toward promotion. Order up smoke from
the mortar squad, HE for those dug in units. Take the objective and you
might make Major someday. Just don't step on a land mine.
Comes with House to House game map, more than 10 scenerios, on 2 cassettes, or all on 1 disk... $29.95. (Disk included.)

search and attack aircraft then hope for the best. Find the enemy fleet,
then pick the targets: Akagi, Soryu, Kaga, Yamato and others in this
historically accurate game. Relive history, Admiral, and it won't be any
easier this time around. Anchors Aweigh.

attacked in the Ardennes, but little else. What is their strength? Their objective?
Who do you send to repair the huge gap In the American lines? What bridges do
you blow? Can you protect the fuel depots? Where are all those Tigers coming
from? When will the weather clear?
Historically accurate, and a real challenge whether'it be against the computer or

A program to help students seek information
Gathering Information From
The CoCo Encyclopedia
Bv Steve Blvn
Rainbow Contributing Editor
This month's article continues the
thoughts begun last month about
information gathering. Today's
students are required to gather more
information than in the past but are
fortunate to have many additional places
to gather this information.
One of the services of CompuServe is
Grolier's Encyclopedia. Entering GO
AAEv/\\\ get you to this CompuServe
feature. The students may call this ser-
vice and let CompuServe search the
encyclopedia database for the topic need-
ed. The various places in the encyclope-
dia that have information on the topic
needed will be displayed and the student
may choose to view any or all of these
sections.
This type of electronic search is fast
and efficient. It should not. however,
replace completely the ability to look up
in a standard encyclopedia one's own
information. It is similar to the advent
of inexpensive calculators. Even though
everyone can afford to own a calculator,
it is still necessary to know how to do
(Sieve Blyn leaches both exceptional
ami gij led children, holds two master's
degrees and has won awards for the
design of programs to aid the handi-
capped. He and his wife, Cheryl, own
Computer Island. )
most of the computations on your own.
Looking up information in an ency-
clopedia would be a good deal easier if
they all consisted of 26 volumes, one for
each letter. Of course, this is impracti-
cal. Encyclopedias have fewer than 26
volumes and combine information on
several letters. There are fewer topics
that begin with the letter X than with the
letter A. Letter A topics may cover an
entire volume on their own. The infor-
mation that begins with the letter X.
however, is almost always combined
with the other letters surrounding it.
Volume 12. for example, may contain
information that begins with the letters
W. X. Y.and Z.
Volume 12 might, therefore, appear
as 12 W-Z. It is sometimes confusing to
newcomers as to where the information
for X and Y is. It must be clearly
explained to students that they may
have to search for where their initial
letter is contained.
It's often even more confusing to stu-
dents to decide which letter to look up in
the first place. This requires both
thought and practice. The Color Com-
puter, for example . might be listed in a
computer encyclopedia under C for
computer, T for Tandy. M for micro-
computers, or even M for Motorola
the developer of the 6809 chip. A stu-
dent must learn to think ol the various
possibilities where the information
sought might be contained and then
narrow down the choices to the most
logical few.
Names are located by the first letter of
the last name. Lonnie Ealk, for exam-
ple, would be found in the volume con-
taining F's. The gold rush, however,
would be found under the G's rather
than the R's. Cars present an even
greater challenge as they are usually
found under the A's for automobiles.
Fast sports cars would also be found
under A's for automobiles. This is not
apparent to many students. They might
very well waste a lot of time searching in
the F. S and C volumes for this informa-
tion. They should be encouraged to first
reason out the most logical choices of
where to find their information.
This month's program draws an en-
cyclopedia set and then presents a topic
to be looked up. The student's task is to
press the number of the volume that
would most likely contain information
on that topic.
We have included 10 topics lor the
children to consider. Please consider
thisa starterset ofquestions ratherthan
a finished set. Either delete and replace
our questions or add to the existing
questions. A thinking skill such as what
is being considered here cannot possibly
be mastered by a student with any given

set of 10 or 20 questions. It should
rather be a skill that builds up to more
and more difficult questions to be an-
swered.
Lines 60-430 contain the strings to
draw the letters and numbers needed.
Lines 470-720 draw the encyclopedia
set. Lines 730-830 ask the question
"Which book contains information
about ..." Line 810 sends the program
to 950 to select from one of the 10 given
questions. Lines 880 and 890 decide if
the answer is right or wrong and print
the appropriate message.
Press ENTER and the program returns
to Line 440 to check the counter and
give the next question. If the counter
indicates that five questions have been
done, then a report card is shown on
Lines 1080- 1 1 10. You may continue or
end the program at this point.
The lines that are user modifiable are
Lines 970-1060. They contain the ques-
tions and answers. There are three parts
to each line. QQS represents the ques-
tions. Each letter of the alphabet stands
for its picture. Thus, SAM is repres-
ented by SS+AS+MS. AN is the correct
volume number. RAS represents the
picture for the correct number. The
numbers go from N1S-N9S. These are
the lines that we encourage you to mod-
ify or add to for your own purposes. Of
course, the R value on Line 950 should
correspond to the number of questions
used.
We encourage you to alter our pro-
grams in any way that may help your
children or students. As a side benefit to
altering programs written by others,
you also increase your own program-
ming skills.
Before leaving this month, wc would
like to pass on some educational news.
The College Board Association has de-
cided to include a programming exam
in its Advanced Placement Test Sche-
dule. These are tests that high school
sepiors can take for advanced place-
ment in college. The programming lan-
guage that they have chosen for the test
is pascal, rather than BASIC.
This means that to receive advanced
college credit, our high school students
will need to become proficient ip PAS-
CAL. At Computer Island, we have been
using the pascal version for the Color
Computer offered by Deft Systems Inc .
We find it easy to get started and use.
The manuals are extensive, clear and
complete. We feel that high school stu-
dents would obtain a very good back-
ground in PASCAL by using this product.

SCOREBOARD POINTERS
In conjunction with the rainbow's Scoreboard, we offer this column of
pointers for our game-playing readers' benefit. If you have some interest-
ing hints and tips, we encourage you to share them by sending them to
the Scoreboard, c/o the rainbow.
COINING A PHRASE
Scoreboard:
I have heard of many Adventurers who
are stuck in the pit in game I of Tlie Amazing
Adventures of Karrak (THE RAINBOW, Feb.
"84). To pass the pit you have to put a coin in
the slot, but there's no way to get the coin (at
least I haven't found one anywhere in the
listing). Add to the end of Line 1 10 of Listing
2 (game 1) the following:
:C(7)=2
This change will reveal the secrets that
await Karrak in his journey.
JyriJ. Virkki
Rio Piedras, Puerto Rico
GETTING DOWN TO ESSENTIALS
Scoreboard:
For everyone who wants to know the
essential words of the different Adventure
games such as Bedlam. Raaka-Tu. Pyramid.
etc.. simply type in the following:
FOR X = 1536 TO 16383: POKE 1024
+(X AND 511). PEEK(X): NEXT
The scrolling can be stopped by pressing
shift @ and started again by pressing any
key. You will notice that meaningful words
appear by the end of the programs.
Georges Pagace
St. David de I'Auberiviere. Quebec
PLANEBUSTERS
Scoreboard:
The method of killingall planes in Zaxxon
(described in Oct. "84 "Scoreboard Poin-
ters") works fine, but there is a much simpler
way.
After you are safely over the fortress wall,
before the planes come, position your joy-
stick all the way up and all the way to the
right. Your ship will move all the way down
and to the right. Then fire like a hyperactive
bongo player. This works perfectly on all
levels, as long as you keep firing. Also, to
destroy Zaxxon himself, position your ship
at exactly 2'/. on the height scale and fire at
least six shots on the missile under his left
arm — this is his only vulnerable spot.
To those who have 32K or 64K CoCos
and are trying to solve Bedlam or Raaka- Tu.
try the following:
1) Turn onCoCoand TV
2) POKE25.64:POKE I6384.0:NEW ENTER
3) Enter the following short program:
5 FOR X= 1 5000 TO 16383
10 PRINT CHR$(PEEK(X));
15 NEXT X
4) CLOADM "WHATEVER" ENTER and
wait for loading
5) RUN ENTER
At first you will see only garbage, but wait
for a few moments and you will see all avail-
able commands. (This method may also
work for Pyramid.)
If you have almost solved Raaka-Tu. but
only get out with 20 points, this is not
because you had to drop the coin. You can-
not complete the Adventure without drop-
ping the coin. To get the points that you
need, in the form of a precious gem. EXAM-
INE around the gargoyle's chambers.

KEY TO THE PYRAMID
Scoreboard:
I have finally solved Pyramid and. to
whom it may concern, you must get the jewel
encrusted key in order to open the sarcopha-
gus. Also, the plant that's murmuring "water
. . . water . . ." is in the bottom of the west-
ern two-pit room.
I need help in solving Madness and the
Minotaur, and I've gotten to the wizard's
image in Dungeons of Daggorath. but I just
can't figure out how to kill it. Also, if anyone
could help me in getting to level 4D in Time
Bandit. I'd greatly appreciate it. If you can
help me in any way, contact me at 582
Sharpners Pond Rd.. 01845. Ifyou need any
help with anything, I'll be glad to help out.
Jeff Murphy
North Andover. MA
Scoreboard:
For everyone having trouble with Dun-
geons of Daggorath. here are some tips.
If you are having trouble incanting rings,
look up the word for the kind of ring it is.
[For example,] for the Vulcan ring you
would look up [the meaing of] Vulcan and
then type INCANT (blank); whatever the
word in the blank is will have to do with
Vulcan. Do the same way with the other
rings. (Gold rings cannot be incantcd.)
Ifyou are still trying to defeat the wizard
clone, spare all of your incantcd rings. Four
hits with them will kill the clone. Be sure to
have the sword in one hand and the remain-
der of the incanted ring in the other. You will
be transferred to the fourth level with only
what is in your hands and the torch you're
using.
To kill the real wizard, use the jeweled ring
after it's incantcd and the elvish sword. Doit
in a "hit and run" manner. After the wizard's
killed there is one more thing to do before
you see "Behold! Destiny . . ."
Nathan Russell
Minco. OK
MITIGATION FOR MADNESS
Scoreboard:
I have managed to find some information
for Madness and the Minotaur. It is a list ol
objects needed to pick up other spells,
objects and to kill monsters. There is also a
way lo gel out of the maze. To gel this list
send $2 (Canadian funds if possible) to P.O.
Box 2914, TO A 2 MO.
Larry Pla.xion
Medlev. Alberta
FOR SOLUTION SEEKERS
Scoreboard:
I'm an Adventure player and I've solved
quite a lew games. If anyone has any ques-
tions send a SASE to Route I. Box 125,
3801 1. The following games are ones I have
solved: Raaka-Tu. Pyramid. Bedlam. Ad-
venture Trilogy. Cimeeon Moon. Dungeons
of Daggorath and most of Madness and the
Minotaur (I think I have all the treasures,
but I've never gotten them all after killing the
monsters, gelling all the spells and opening
one crypt).
Does anyone know where the potion is in
Raaka-Tu and what it does? You don'l need
il lo get 50 points.

LOTS O' LASERS
Scoreboard:
I have played Cavern Copier (THE rain-
BOW, Feb. '84) especially with the program-
ming and I have a few lips for those that
can't seem to beat the hordes and get the
artifact. You can receive an infinite number
of lasers by editing line 752 and changing F
= F + I in'lhe third line of 752 to F= F+0.
This w ill give you as many lasers as you wish
lo use.
I can't seem to get the key in the electrical
therapeutic room in Bedlam. If anyone can
give me a few hints, write me at 64 Mi. Bethel
Rd., 07060.

Scoreboard:
I own a TRS-80 CoCo 64K. Is there a

thai rolls up characters and allows you to

AN ACTIVITY OF
CHILDREN'S TELEVISION WORKSHOP
Put Radio Shack's exciting
Color Computer 2 and the best in
children's software under your
tree this Christmas. You'll save
money now and delight your fam-
ily throughout the year!
The Perfect Gift
at the Perfect Price
Now you can save up to $60 on
the remarkable Color Computer 2
and enjoy home computing with
your children anytime. Just attach
the Color Computer 2 to your tel-
evision set and Radio Shack's
easy-to-understand instructions
will have you and your children
programming right away— even if
you've never used a computer
before. Or select from dozens of
useful programs and colorful
game packs to make the Color
Computer 2 the perfect computer
for everyone at home!
Choose the Model
Right for Your Family
Radio Shack offers three af-
fordable models of the Color
Computer 2. The 16K Standard
BASIC Color Computer 2 in-
cludes a typewriter-quality key-
board, compact styling and
built-in BASIC language capabil-
ity. BASIC is a versatile computer
language your children may al-
ready have used in school. Now
they can write their own programs
and create spectacular eight-color
graphics at home. And the 16K
Standard Color Computer 2 is
supported by a full line of quality
Radio Shack accessories, so you
can expand as your children's in-
terest and skills grow.
The 16K Extended BASIC
Color Computer 2 includes the
features of the Standard Color
Computer 2, plus advanced pro-
gramming capabilities made pos-
sible by the Extended BASIC
language. You'll be able to write
more sophisticated programs
and create high-resolution color
graphics using simple one-line
commands.
Color Computing for
Advanced Programmers
The 64K Extended BASIC
Color Computer 2 has the power
and performance for advanced
home and small-business use.
The 64K Extended Color
Computer 2 can easily see your
children through high school, col-
lege and beyond, or stay at home
with you to help out with invest-
ment analysis, home budgeting,
business records and more. With
the built-in Extended BASIC, your
family can take advantage of 32K
memory, enough for many ad-
vanced programs and computer
games. Add an optional disk drive
and operating system and your
family can access 64K.
A Terrific Gift
to Give or Get!
Take advantage of Radio
Shack's special holiday savings
on the Color Computer 2. It's a
gift your children will use and en-
joy, and a handy tool you can use
at home or work.
Bring Home the Best in
Educational Software
Your children will enjoy Radio
Shack's selection of educational
software as much as the Color
Computer 2. You'll enjoy knowing
they're using carefully prepared
educational software from the
names you can trust: Children's
Computer Workshop (a division of
CTW— the creators of Sesame
Street'"), Walt Disney and
Spinnaker. Choose from pro-
grams to help improve reading,
writing, math and science skills
for children age 3 and older.

Screen Pixels: The most common measure of resolution (HxV).
Characters per screen: The maximum number of characters rec-
ommended to place into the display area. Monochrome monitors are
recommended for word processing (80 characters x 24 lines).
Bandwidth: The speed at which a monitor can accept data from the
computer. Video bandwidth constrains the screen refresh rate,
active display area, pixel resolution, and image sharpness. Higher
bandwidths allow steadier, sharper, more detailed images.
Dot pitch: The distance between the holes in a monitor's shadow

THE RAINBOW
REVIEWING
DAPPER
Editor:
We would like to congratulate Donald D.
Dollberg on his excellent review of our disk
zap program. Dapper. The review, which
appears on Page 212 ol ihe October rain-
how, is highly accurate. Normally even a
\ery lavorable review has some error or mis-
understanding. In our review of Mr. Doll-
berg's review, we could find no errors.
I he version ol Dapper, reviewed by Mr.
Dollberg. was the very first release of that
program. A new. improved version of Dap-
per has been released. The latest version of
Dapper has three additional commands.
These are HIDE. SEEK and SORT. HIDE
makes a copy of the allocation table and the
directory. If the information in track 17 is
destroyed or becomes unreadable, it can be
retrieved from hiding by using the SEEK
command. The last new command. SORT.
sorts the directory.
In all. Dapper now has 14 commands.
They are:
BACKUP — backs up a disk to tape
CERTIFY — certifies disk granules
DIRECTORY - lists the directory
DUMP — prints a sector in ASCII and
Hex
END — exits the program
HELP displays commands information
HIDE copies track 17
MAP maps the granules of files
MOVE — moves a granule
RESTORE restores a disk from tape
SEEK retrieves track 17 from hiding
SORT sorts the directory
VERIFY verifies the granules of files
ZAP enters the zap subsystem
The cost of Dapper, however, remains the
same. It is still SI 4.95.
Ihe review may have lell the impression
that the "wild card" option lor filenames
only applies to the DIRECTORY command.
In lact. this feature may be used on any
command which accepts filenames, i.e..
DIRECTORY. MAP and VERIFY. Addi-
190
tionally. the impression may have been left
that only DIRECTORY could be abbre-
viated to three characters. In lact. all com-
mands can be entered with three characters.
Wcare obviously pleased with such praise
as "a little gem. ""perlormed flawlessly" and
"excellent supporting documentation." We
were gratified that Mr. Dollberg would
"highly recommend Dapper."
Thank you for your excellent publication,
and lor the quality reviews.

TAXAID
Editor:
[In reference to Alpha Bytes TAXAID
rev lew] I have not at this point checked, but 1
am sure that Mr. Odlin is correct that there
are some incorrectly spelled words in the
program. Somehow this does not distress
me. I do not lay claim to being a speller or a
typist. However, with the help of "Mr.
Webster." I can probably gel most of these
corrected before the release date ol Jan. I.
I think it is unfortunate Mr. Odlin tries to
impose his views of what is aesthetically
pleasing on paper and screen, and thereby he
does a disservice to your readers in limiting
his review to trivia rather than what the pro-
gram does with the 280 variables used more
than 1 100 times.
When was the last time Mr, Odlin com-
pleted a 1040 with several schedules? If
within recent limes. I believe his conception
of slow would be more than somewhat
changed. Ii runs faster than a trip to those
well-known brothers who do one's taxes for
a considerable fee.
John M. Gregg
Alpha Byte
Editor:
Alpha Byte's program is slow, awkward
and incomplete. Programs displaying the
opposite qualities exist in abundance, for
other operating systems, and unless one
desires to maintain CoCo in a sort of
"ghetto." there is no need to pretend things
like TAXAID are adequate equivalents for
such programs.
As for his attempts to pick fault with my
prose, they would be altogether beside the
point, even were they based on something
more serious than personal annoyance and
an inclination to thumb through obsolete
grammatical texts in search of tomatoes to
throw.
R. W. Odlin
ALDARON
Editor:
I just received a copy ol [Dale Shell's]
review of our A Idaron game (October I9N4).
I want to thank [Mr. Shell] and the other
rainbow reviewers for the great job they've
been doing. Ihe review was lair and honest,
and it's evident [Mr. ShellJ spent quite a bit
of time playing the game and giving it [his]
serious attention.
I should mention that a slightly enhanced
disk version is now available. The response
from our customers on this game has been
overwhelming; it seems people appreciate
the 180-plusword vocabulary, and the intelli-
gent, detailed descriptions. A sequel is being
planned (the further adventures ol . . .),
incorporating customer suggestions. We in-
tentionally make it difficult to complete our
games -- otherwise only novices would
enjoy it and no one would want to play it
twice. One can solve one of our Adventures,
play it again, and discover do/ens of new
rooms in the process.
For you and anyone else who might be
stumped by Aldarott. here are two hints:
1) Don't forget about the back door; and
2) if you translate the Latin into English,
you'll discover it's a magic phrase (and
incidentally, a quote from Shakespeare).
Good luck, and thanks again.

Wizard Gives CoCo More
Character
Among CoCo's serious word-processor users, Telewriter-
64 is without a doubt, one of the easiest, most efficient and
most flexible programs on the market for any computer.
Two years after it was introduced, Telewriier-64 remains an
almost indispensable tool for many serious writers and
programmers.
The only flaw, which really hasn't bothered most of us,
has been the lack of a true on-screen, upper- and lowercase
display with descenders.
Enter D. Dean Rector, of Knoxville, Tenn., who felt that
it was time to give Telewriter a "little more character" when
he found the screen difficult to read for long periods of time.
Dean is one of those CoCo users who cannot resist delving
into a program when they believe something can be
improved.
Thanks to Dean's efforts, it is now possible for you to
have a new on-screen font, plus real descenders for Telewri-
ier-64. And as one who currently is typing this review using
Dean's new Wizard program, 1 can attest to the relief that
innovation offers the eyes after long periods of keyboarding.
People who proofread for their livelihood will find Wizard
especially helpful.

The program, which you can easily adapt to your existing
cassette or disk copy of Telewriter 64, also includes option
carriage return marks, which are very useful for locating
run-on spaces at the end of lines and between lines. They
allow you to count spaces between text lines and they are
essential for reformatting non-standard text such as
columns, tables and poetry. They're also useful if you write
programs, in which a misplaced carriage return can spell
disaster.
Complete instructions for modifying your existing Tele-
writer-64 programs are spelled out in detail in 14 pages of
documentation that are included with your purchase of
Wizard.
Folks who are easily confused by terminology of pro-
grammers will be relieved to know that you do not have to
worry with 'aren't we clever' explanations that leave you
wondering whether you will ever get the program to work
for you. The author tells you step-by-step in easy-to-
understand directions what you need to do. You will experi-
ence problems only if you try to skip over the directions like
this writer in his hurry to make the modification.
As far as I could determine, Wizard did not affect any
other aspects of my existing program. Although the author
warns that "occasionally there will be a printer that does not
respond to Telewriter-64 line feeds." 1 use an Epson RX-80
F/T and did not experience any problems. Suggestions are
included should you run into difficulty, plus there's a 30-day
return policy that enables you to return the program and
receive a cash refund for the full purchase price.
Wizard is another CoCo winner, proving that we, as a
user group, will not settle for less than the best in getting the
lull potential out of our favorite computer. 1 know you will
appreciate these innovative enhancements to Telewriter-64.

THE RAINBOW December 1984
Software Review.
Dynamite + Is A Powerful
Disassembler
By Dale L. Pucketl
mid
Bruce \. Warner
If you've ever disassembled a machine language program,
you know the frustration of trying to make sense out of the
listings of dozens of labels and system calls that went into the
assembly source code listing. You can spend weeks putting
in labels and system calls (ROM calls for Disk BASIC) that
appear to be nothing more than a branch instruction to
some location in memory. You can spend additional weeks
putting in labels and dissecting a ROM call, and still have 10
percent of the program remaining a mystery.
Worse yet, when you finally figure out Radio Shack's
ROM and feel you're ready to go on to more serious applica-
tions for the Color Computer with FLEX or OS-9. you need
to start all over again and figure out system calls for those
operating systems.
Now you have three sets of system calls that confuse you.
and you're still in the dog house. You must decompose all
those foul data tables that keep rearing their ugly heads
again and again. How will you ever get free of this tedium,
and move into the serious modification of your existing
software for more effective operation'.'
Dynamite + to the rescue! It is a disassembler that gives
you more than you ever thought possible from a disas-
sembler on the Color Computer.
Dynamite + comes on a single diskette to run on the Color
Computer under OS-9. Other versions are available for
standard OS-9. UniFLEX and 6809 FLEX (including FHL
FLEX). It disassembles both 6800 and 6809 object code, and
code originallv produced under TRS-80 Color Computer
Disk BASIC (CoCo DOS) and FLEX! Now with OS-9, O-
PAK and Dynamite +. you have a serious disassembler for
all your CoCo programs.
What amazed us most of all is that the resultant source
code from the disassembly can actually be reassembled and
executed. Although this is not an industry first, it's the first
we've seen on the CoCo.
Reassembly is possible because Dynamite + produces
labels automatically from any memory references within a
program. Better yet. those addresses that are outside the
actual program (system calls) are defined by EQU state-
ments grouped together at the start of the text file. You can
define label names as your own standard label names as well,
giving super meaningful disassemblies. You have control
over the entire disassembly by defining any block of code as
data.
When getting started, you will have to get accustomed to
the requirement to perform multiple disassemblies to obtain
your completed source code listing. 11 you're looking for a
disassembly without any work on your part, think again.
Dynamite + requires a lot of work on your part. The divi-
dends, though, are well worth your efforts, in the form of
disassembled listings that reflect assembly source code down
to the last system call.
Speed is not one of Dynamite +'s strongest suits. The
work is. however, much easier with Dynamite +. Each disas-
sembly step requires three passes of the program, and the
disassembly requires a minimum of two steps to get a usable
listing. A complete disassembly will require six steps, and a
lot of patience on your part. The end product is worth the
wait, and your extra work will provide you with more than
you ever hoped for from any disassembler.
This package doesn't stop with the Dynamite disas-
sembler. It comes with three additional utilities in the
package.
You'll get a memory save utility (SA VEM). This is very
different from OS-9's SA Kfcommand. What makes this so
valuable is that it allows you to save a block of memory in
CoCo DOS, OS-9, FLEX or Motorola format. It's starting
to look more and more like this is the missing link to give
you all the utilities you'll ever need.
You can then use the Convert utility to convert an object
code file on disk from either Motorola or OS-9 format to
CoCo DOS or FLEX format. And finally, there is an XREF
utility, that lists all line numbers of an assembly listing that
refer to a label in your disassembled listing.
There was a serious problem with loading Dynamite + on
the Color Computer. It kept telling us that we weren't using
a Color Computer. That presented a problem, because we
were using a Color Computer (an E-board, self-converted
to 64K). Not being overly fond of such problems. Dale
found the solution. We loaded CCIO (we'd been using
Word-Pak and hence deleted CCIO from the boot). We
tried to load Dynamite + on his G1MIX and came up with
another problem. We then loaded CCIO on the GIM IX. and
it still wouldn't run. The program seems to do some checks
to verify which machine it is on, so be aware that if CCIO is
dumped and Word-Pak is your normal output, you will
have to load CCIO while running Dynamite +.
At the cost of other OS-9 software, you'd expect to pay a

Stomp Your Opponent With
Stomp — Just For Fun
Stomp is a 32K Extended Color basic program with
PMODE 3 graphics that uses one or two joysticks, and/ or
keyboard. It is designed to be played by two to lour players.
aged six to 60. More players mean more chances to stomp
your competition. Players that enjoy strategy games, as well
as plain old revenge, will enjoy this game. It is played on a 15
by 17 grid with 15 squares removed from the center. Each
player is given a representative symbol (i.e.. a plus sign,
circle, or triangle) and an equal number ol "chips," always
totaling 240 in number. The object of the game is to be the
first player to run out of chips. To rid yourself of your chips,
you must move through the grid and on each square that has
not been passed through previously, leave one chip. The
square is then marked with that player's symbol. You can
give your opponent chips by stomping their present position
which is marked by a blue symbol. When stomping an
opponent, the number of squares passed to get to their
symbol on that turn is totaled, and many chips are sub-
tracted from your total and arc given to your opponent.
Each player's name is input to the program, and. in turn,
each player is identified by name and asked to roll three
electronic dice by pressing a key or joystick button. On your
screen you watch representations of dice rolling and ran-
domly stopping. In each turn the players must move their
symbol for each of the numbers shown in a horizontal/ verti-
cal/ horizontal, or, vertical/ horizontal/ vertical pattern. If
the dice roll was 6.2.3: then the move would possibly be six
squares right, two squares up, three squares left. Each
number must be used on time. If it is impossible to use all
three numbers and stay within the grid then you must give
up your turn. When you gel rid of all your chips your symbol
stops and you cannot move any farther, although your
opponents may still continue to stomp you and give you
more chips to put you back into the game. Each of your
opponents have one more chance to try to stomp you before
the game ends.
Instructions on loading are simply written and complete.
The cassette tape loaded without any trouble and lakes
about one and a half minuics lo load.
The instructions suggest that players between the ages of
six and 60 should enjoy this game. Our seven-year-old lost
interest quickly; he just didn't have the concentration and
patience to play the entire game. On the other hand. 1 have
been carefully plotting my strategy for a match of strength
with the computer wizard of our family, who is currently
away on business while mom is holding down the fort: and
writing RAINBOW reviews, too!
A definite plus for this game is that no special timing or
coordination skills are needed to be a successful player, so
even grandma and grandpa can enjoy our CoCo and pit
their strategies against the younger generation. Our family
always seems to be plagued by a tight budget-, and the S24.95
price seems to be a little steep for this game. I think Slump
could be improved by making the grid squares a little larger
to reduce eye strain from the many hours of plotting
revenge.

Freeform — A Flexible,
Menu-Driven Database
I like database programs. This is most probably because,
as an essentially unorganized person, a database lets me
organize thoughts and ideas. It lets me keep my "fingers on
facts" — something 1 do not do very well in my head.
(In my own defense. I must say that there are a lot of facts
in my head. I am one of the better players of trivia games,
but that is another story.)
Such things as telephone numbers, addresses, appoint-
ments and the like confound me. Yet, as with most busy
persons. 1 do not have a lot of time to mess with setting up
complicated database programs, such as something like
dBase requires.
I prefer what are called "menu-driven database pro-
grams." These are the ones that give you a lot of options on
the screen, and let you set things up the way you want them
to be. One of the problems with menu-driven systems, how-
ever, is that they will usually only let you set things up their
way.
Freeform, by the United Software Company for OS-9
systems, meets the two criteria that I consider most impor-
tant in establishing a database. It is menu-driven, but is
structured — as the name implies — in such a way that you
can design a database pretty much, well, free form.

What I am saying is that Freeform is flexible, yet easy to
use. This is no small programming task, yet United Software
Company has done it.
They do it with a concept I have not seen before — the
concept of "electronic cards" in an electronic file. Each card
has 13 lines of text, and you can have multiple cards for any
given situation.
In working with Freeform, 1 followed their tutorial to set
up an appointment calendar — not usually an easy feat. This
is simply because, as far as I am concerned, there are two
important criteria in an appointment calendar: the ability to
show appointments by day but, also, to find some single
appointment that I just know is sometime this week, but
forgot exactly when.
Freeform makes this very easy because it uses a very
different method of selecting key words in any entry. With
all other database managers I have seen, you set up a very
structured system and then make your data fit. In this
example, you can set up a database with days, times, per-
sons' names, activities and the like. But you have to define
the length of each of these entries. You end up either wasting
a lot of space or making the whole data entry process very
complicated.
Not so with Freeform. This is because once you have
typed in whatever information you need, you go back and
select your own key words to search on. To illustrate this, let
us suppose you have an entry called "Meet Mr. Jones About
Taxes." You could highlight both "Jones" and "Taxes."
Then, when trying to remember when it is that you are
supposed to meet Mr. Jones, you can search on either
"Taxes" or "Jones." Neat!
Each card can be titled, and you can have up to nine pages
for each card. Since each page holds 13 lines of 37 characters
each, this adds up to a lot of information available for any
day.
Of course, a calendar is not very useful unless it can be
printed out. This is accomplished simply, with each card
printed as a separate entity. It might be nice to buy some of
those continuous index cards available from a number of
places and use them for Freeform printouts.
It is important to mention that you can use "wild cards" in
your search process. So, if you wanted a list of, say, all "bid
specifications. ""bid meetings"and"bid lettings,"you could
search on "bid *"and get all three.
One thing I did not like, however, is the way in which
search results are reported. When you search fora key word
or phrase, Freeform responds with the names of the cards on
which the information is contained. 1 would have liked it
better if it just went to fetch the card itself and display it on
the screen.
Freeform, by TMP Software lor OS-9 systems, meets the
two criteria that I consider most important in establishing a
database. It is menu-driven, but is structured - as the name
implies — in such a way that you can design a database
pretty much. well, free form.

Protect Your BASIC Programs
From Piracy
With Hide-A -BASIC
If you are writing software that you are planning to
market, one of the things that might cross your mind is: Will
software piracy make my efforts a waste of time? II you are
writing a machine language program, there are many ways
you can protect your work. In BASIC", however, there is not
much you can do. There is. however, some hope now with
the introduction of some new software.
Hide-A-BASK is a utility program that will allow you to
completely protect your BASIC program. It does this by
creating a machine language loader program which will
auto-execute, and then load and run your basic program.
Several options are available, which make it next to impos-
sible to copy or even look at your program.
Starting up Hiile-A-BASIC is accomplished using
CLOADM. II you have a disk system, you must first unplug
yourdisk controller. The program is protected by itself, so it
is run automatically, The main menu then appears, which
presents you with several options.
The first option that you would choose is Define Parame-
ters. This option allows you to select the level of protection
you want your program to have. You can disable the Reset.

BREAK, and CLEAR keys, as well as assign new names to
some of Basic's commands. I hese commands include,
among others. CSA VE, LIST, PEEK. POKE, and Edit. By
changing the names of these BASIC commands, there is
practically no way for your program to be listed or copied.
The function of the BRtAK and CLEAR disable is obvious.
They don't work. In fact, the Reset button will just RUN
your program all over again. If you don't disable the Reset
button, you will get the familiar OK prompt if you use it.
Here is where the changing of Basic's command names
comes into play. Type LIST, and if you have changed its
name, you will gel an SN Error. When you decide to change
the names, you enter whatever you want as the substitution
for it. For example, you could have substituted SHOW for
LIST, and if you were to type in SHOW, your program
would then be LISTed. Naturally, anyone buying your
software would not know the substitute names that you
used, so trying to guess them could take quite a while.
Once you have chosen all of the options that you want,
you would select another main menu option that will save
your customized auto-execute loader to tape. Next, you
have to shut off your computer and turn it back on again,
and load in your BASIC program to be protected. Saving
your program to tape involves a simple POKE and an
EXEC. This places a copy of your program immediately
after the auto-execute loader you created before. Once you
are through with all of this, you will have a protected copy of
your program on tape, which can only be loaded into the
computer using CLOADM.
Hide-A-BASIC is very easy to use, and the documentation
clearly describes how to create your protected program. It
does work, and there did not appear to be any way that a
protected program could be copied, although 1 suppose
someone might be able to figure it out given enough time.
The only thing I did not like about it was that you have to
unplug your disk controller to use it. I guess this was a
necessary evil, since it also disables all of the Disk BASIC
commands. If you are considering marketing cassette-based
basic software. Hiile-A-BASK could be your ticket to
increased sales.

Deputy Inspector
Will Organize Your Disks
1 know thai program is on this disk somewhere! IT only
that directory wasn't so long and jumbled! Enter the deputy
- Deputy Inspector, that is. This directory utility by Son-
burst Software can help you sort out the mess on that disk
fast and easy.
The package is supplied on disk with a 3 1 -page spiral
bound manual, including an index, which is more than
sufficient. The program consists of a BASIC loader and a
machine language routine written for 64 K Color Computer.
A list of variables used in the BASIC loader program is given
in the manual along with their possible values. The default
values are contained in data statements within the loader
any may be changed to suit your particular needs. The
variables you may change arc: Baud rate, sort sequence by
program extension, and stepping rate. After changing any
default values you may then save the loader program again
for future use. The Baud rate may also be changed on a
temporary basis from one of the main menu options.
You begin the program simply by typing RUN DI. The
main menu appears offering six options. A seventh option.
'K'. toggles a keyclick on or off but does not appear on the
screen as an option. Following is a listing of the remaining
six main menu options:
D - displays directory submenu containing eight
additional options
F displays format and backup submenu contain-
ing three additional options
O allows selection of single default drive
M - toggles between multiple drives or single drive
B allows the default Baud rate to be temporarily
changed
V toggles the verify write operations on or off
The 'D' and '¥' options are the two providing the useful
utilities. From the directory submenu you may do the
following.

CHILD'S PLAY
Mouse Technological Software For The Color Computer]
Ted Malaska. President
& Co-founder of TCE
Programs Inc., announced
today a new division for
the development of busi -
ness software.
The new division will
distribute a series of
machine language business
programs, under the name
Child's Play beginning in
the first half of 1985. The
Child's Play series will use
mouse technology and
what Mr. Malaska termed
"Flna t i ng Overlays", to
control the operations
within the program.
When asked why the
name Child's Play was
selected for a business
series, Mr. Malaska re-
sponded: "Floating Over-
lays will make the program
operation seem like Child's
Play . compared to other
business software of today."

Using the above features you may then rearrange your
direetories in any way. They may be alphabetical, sorted by
extension, or moved around one file at a time. You may even
place multiple copies of a file on the same disk using the
same filename if you wish.
The format and backup submenu allows you to format
one or more tracks; perform a standard disk backup: or
perform a collated backup.
Combining the directory features with the collated backup
feature, it is possible for you to place a file in a particular
location in your directory and perform a collated backup,
thus placing your desired file on specific tracks of your disk.
A collated backup does this by taking your first directory
entry and relocating its gran allocation to start with the first
gran on track 0. The second entry will be saved immediately
following the first and so forth. By counting up gran alloca-
tions, you can actually place a file on a specific track by
relocating it in your directory. This can minimize your drive
head movement and improve on loading time for large files.
Also included on my copy of the disk is a program called
NOCOI BAS. At first 1 thought this was part of the Deputy
Inspector, but after listing it. it did not appear this was so. It
will execute as a stand-alone program and is a number
converter program with its own menu. Given the most sig-
nificant and least significant bytes in decimal, it will give you
the number in decimal, binary, and hexadecimal. You may
also convert from decimal, binary, or Hex to the remaining
number types not used as the source number. You may also
scan memory between any two addresses, routing it to a
printer if you like. This program was never mentioned in the
manual so 1 assume it was a minor bonus.
The only leature ol the Deputy Inspector I was unable to
lest was the printer options since 1 do not have a serial to
parallel converter to interface my computer and printer yet.
1 can only assume that these features will perform as well as
the rest of the program has. If you have a need to organize
your directories or rearrange your disks. Deputy Inspector
should do the trick for you.

The Pond Shapes
And Sharpens
Problem Solving Skills
The Pond. Irom Sunburst Communications, is an excel-
lent program to leach pattern recognition, prediction, and
logic. It is suitable for second-graders through adults, and
requires 32K of memory and a disk drive.
The object of the program is to help a frogjump through a
maze of lily pads to a magic pad on the other side of the
pond. To do this successfully the student has to identify the
pattern of directions to be followed in order to cross the
pond. The patterns may be two, three, or four steps accord-
ing to the level of play selected.
At the beginning of the program, the student may select
either a practice or game mode. The practice option allows
the student his/her choice of any of six different ponds.
Each successive pond is a degree of difficulty harder.
The first two levels utilize two-step patterns, the next two
have three-step patterns and the final two patterns require
discovering four-step patterns. The odd numbered patterns
have only those pads necessary to form the pathway to be
followed; the even numbered patterns have extra lily pads
on the pond to make it more difficult to discover the pattern.
The screen shows only a portion of the entire pond at any
one time. The frog can be moved within the pond by using
the four arrow keys. If the student needs help. she. he can
press the zero key and get a view of the entire pond. Once the
student believes the pattern has been discovered, the CLEAR
key is pressed and the program prompts the student to enter
the pattern using the arrow keys and the number keys to
describe the pattern (e.g., two right, four up). The ability to
erase keying mistakes is built into the routine.
Once the pattern is entered, the student may begin execu-
tion of the pattern by the frog. If the pattern is correct the
frog will reach the magic lily pad and visual and audio
reinforcements are given. II the pattern is incorrect, the frog

will wind up in the water and swim back to the starling
point.
Alter the pattern has been successfully or unsuccessfully
executed, the student is asked to do the same problem over
again or select a different level.
1 he game option can be used by either one or two players.
The student(s) may choose their starting level. They must
complete each level three times before moving to trie next
level.
At the beginning of each game, each side gets 35 moves.
Moves are used up as follows: one move for each time the
arrow keys are used to move around the pond, 15 moves for
using the zero key to view the entire pond, and five moves for
entering an incorrect pattern. When students have success-
fully completed three different patterns at one level they will
advance to the next level with another 35 moves added to the
moves they have left.
If the students successfully complete the last pattern, a
frog will appear sitting on a mushroom with a graphics
display ol colors around it.
I reviewed two different distribution packages. One was
geared lor the teaching professional and the other for the
home. The documentation in each package was well-
written, but I would suggest the non-professional purchase
the package for the home as the documentation will be easier
to follow. Each package contained the program on a copy
protected disk.
The game mode allows the student to develop the neces-
sary strategies to complete the game with the least amount of
moves. The student will have to make decisions such as:
should I use the arrow keys to explore the pond, try an
unsure pattern, or use the zero key to view the entire pond? I
feel the game would be excellent as an approach to group
problem solving by using teams of multiple players for each
side.
The animation is adequate. The horizontal and vertical
scrolling of the screen is not really quick, but neither is it
distracting. Asa teaching aid to improving problem solving
skills, the program is top-notch. The astute student will soon
start to use some lateral thinking to discover the patterns
involved in the least amount of moves. The younger student
will profit from the practice mode.
The program loaded and executed properly. The initial
menu allows the selection of a well-written set of on-line
instructions. The instructions were adequate, but I had a
problem in discovering the patterns in the harder levels. For
example, the pattern might be five up. two down and three
right. Once I understood that this happened in some ol the
later levels, it made the game even more challenging and
rewarding.
The Pond, from Sunburst Communications, is an excel-
lent program to teach pattern recognition, prediction, and
logic. It is suitable for second-graders through adults, and
requires 32K of memory and a disk drive.

Super Gemprint For Printing
Your Masterpiece
After spending hours of work with his favorite graphics
editor. Mike Angelo. artist extraordinaire and part-time
dishwasher, has finally created the ultimate in images -
graphics that would make Pablo Picasso envious. Unfortu-
nately. Mike has one minor (major) problem: he can't seem
to convince the critics to come to his studio to see his
masterpiece. It appears there indeed will be no escape from
our hero's dilemma. But wait- from out of the blue comes
Super Gemprint, the wonderful new screen, printer gra-
phics utility from Dayton Associates.
Super Gemprint is one of those programs that can really
come in handy if you ever want to print out some of those
lovely graphics screens the CoCo is capable of making. I
found it particularly useful because of its very large (8" x 11")
printing area, which is printed sideways on a piece of stand-
ard paper. About the only disadvantages of the printout
itself are the understandably blocky "characters" because of
the increase in resolution from the CoCo to the printer, and
the overall length of time it takes to print out the entire
screen (approximately 4:47 to print out entire screen at 9600
Baud).
The good points of the program, however, greatly out-
weigh these minor details. The printout area is. of course,
the major advantage of the program. It also takes up very
can
CDDDn
little space in memory. The major feature in my eyes, how-
ever, lies in the program's ability to specify the color's
representation on the printer. For example, many times
when graphics are printed out normally the foreground and
background colors do not appear in the most pleasing ways.
Many times I have printed out what looked a veritable
masterpiece on my color screen, but it lost an awful lot in the
translation. (Oncea picture of a snowman inverted the snow
to black and the chimney smoke white against a black sky -
yuck!) The writer of Super Gemprint obviously had run
across the same problem. Because of this, the instructions
include a small procedure for modifying the tables to the
correct (best-looking) colors. As they say. the little things
mean a lot.
Overall, Super Gemprint is very well-written and docu-
mented. In fact, the only legitimate complaint I have against
the program really isn't about the program itself — it was the
documentation's constant state of change. It took no less
than two updates from the original (hand-corrected) docu-
mentation to become complete. Now, however. 1 have been
assured that the documentation as 1 have it is complete, as it
indeed appears to be. So, if you are looking for a screen-
print program for your Epson/ Gemini Delta; Radix/etc.
printer, then Super Gemprint appears to be a 'gem-dandy.'

OkiDump:
Screen Print Utility
Oki Dump is a specialized program directed to those
individuals wanting to have their Okidata printer produce
hard copy of a graphics screen. The machine language pro-
gram is configured for either a I6K or 32K computer, but
will only work with the Okidata 80 series without Okigraph.
Both the tape and disk version are the same. However, the
disk version includes a program which allows the user to
find the start of a graphics screen. The disk also has two
sample screen programs which are useful in testing the pro-
gramand printer combination. The screen location program
is listed in the manual lor tape users to type in (however, no
sample programs are included on the tape version).
The disk version's samples proved to be most interesting
and yet frustrating. It took three attempts to get the graphic-
design to print out correctly. The first time through the
printout double spaced: the second time it single spaced but
the first few lines were out of register: the third pass pro-
duced a full 814-inch by 1 1 -inch hard copy. The other picture
to test was a dog with a doghouse. The video is colorful and
the printout, which can be made in either normal or reversed
imaging, is a very good likeness of the video picture.
The program author devotes a couple of pages to getting
hard copy from a particular game. As part of the instruc-

lions for getting printouts from this game, the program
author also notes that there are two major problems with the
attempt to get printouts. The first problem reported is that
Oki Dump might not work with games which do not allow
the program to be stopped with BREAK or Reset. Secondly,
the user may have to find the location of the picture and to
remember that by using the information provided it is possi-
ble to destroy the picture by overwriting. Trial and error
relocating the screen search program is necessary. Also
necessary is rerunning whatever program created the picture
you wanted. In two attempts to get a hard copy ol a graphics
screen Irom another program, one worked as expected and
the other attempt not only blew the picture but also crashed
the disk!
The live-page manual that came with the program is hard
to follow. The program author could have made it easier for
the user if he would have continued putting "command"
instructions on separate lines. The users must pull out of the
middle of a couple of paragraphs the rest of the "commands"
to run the program.

In Assembly Language —
A Must For Any Programmer
As everyone knows, the way to get the best performance
and memory utilization out of your CoCo is to code in 6809
assembly language. Unfortunately, assembly language pro-
gramming can sometimes be a tedious procedure with sim-
ple, common tasks often consuming valuable coding and
debugging time. Professional programmers minimize this
problem by taking advantage of libraries of previously writ-
ten routines called system libraries. In Assembly Language.
by Larry Landwehr. is both a library of useful routines for
the 6809 and an aid for learning 6809 assembly language.
The In Assembly Language package consists of a tape
containing 18 6809 assembly routines and a notebook con-
taining documented listings and associated commentary.
Among the 18 routines are a number of common, general-
purpose routines for keyboard and file I/O, interlace to
joysticks, and string and numeric display. Additional rou-
tines provide functionality for random number generation,
high resolution graphics and sound generation. In practice,
the programmer uses a particular routine by merging its
source code with his own. then assembling as usual. (On
more sophisticated systems, library routines are usually
linked in rather than being assembled in.)
Each of the 18 routines provided in the In Assembly
Language package was developed using Radio Shack's
EDTASM+ editor, assembler and debugger, then stored on
tape in ASCII format. This implies that almost any assem-
bler on the market may be used. The quality of the code and
the in-line documentation were both very good.
The commentary provided with each listing presents some
of the background information and design considerations
that went into the development of the code. When used in
conjunction with a standard text on 6809 assembly language
programming, the In Assembly Language manual provides
an excellent introduction to systems level programming on
the CoCo. Along these lines, the package also includes
several more advanced routines demonstrating techniques
such as threaded code and multitasking.
Overall, 1 was very impressed with the quality of the /;;
Assembly Language package. The routines were well docu-
mented, well debugged and easy to use. In addition, the
commentary provided with each routine provides some
good insight into the inner workings of the 6809 and the
CoCo. For the money. In Assembly Language is a must for
any assembly language programmer.

LOGO Starter:
A Place To Begin
As the name implies, logo Starter is designed as a first
experience with Color logo. It allows the first-time LOGO
user to create interesting figures with single keystrokes (plus
ENTER, ol course). The program does not require a knowl-
edge of the LOGO language nor docs it require typing long
program statements.
The program consists of a series of LOGO procedures and
subproccdures that define specific turtle actions. If you are
lamiliar with LOGO, you know that each procedure must be
assigned a name by which the procedure is accessed (exe-
cuted). By naming the procedures used in LOGO Starter by
individual keys, the authors provide the means to run a
procedure by pressing a single key followed by stroking the
ENTER key For example, pressing 'I.* on the keyboard

Color logo's RUN mode by pressing the *L' key (and
ENTER).
LOGO Starter provokes the thought. "Why didn't I think
of that?" Its simplicity is ideally suited to the LOGO language.
Yet. the program also displays the power of LOGO. From
simple keystrokes, great ideas grow. Since the program is
written in LOGO, it would be very easy to change the proce-
dures to perform any actions that you wish. Parents,
teachers, or any LOGO learner' can therefore alter LOGO
Starter to fit their own wishes or needs. Thus LOGO Starter
can serve as a base (or learning how procedures are con-
structed and how they work. Studying existing programs
and changing them to "custom fit" is the key to learning how
to program in any language. It is particularly effective in
logo for studying simple, visual results of individual
statements.
The program comes with a four-page printout that de-
scribes the program's functions and use. The functions of the
keys are not described in detail. This is unnecessary as the
program is designed for exploration and experimentation.
The user will soon learn to associate keys, symbols, and the
actions that result from their use.
Keyboard overlays are included to provide a means to
identify keys with symbols that represent their functions.
Since a variety of keyboards have been used for different
Color Computer configurations. LOGO Starter includes a
variety of overlays so that each computer version is provided
for. Also included are self-sticking symbols for the lower
three rows of keys. Sticking these symbols to the front faces
of the keys provides quick matching of functions to the
correct keys.
The program provides use of Color LOGOS BREAK.
RUN and DOODLE modes. Keys provide the usual FOR-
WARD. BACK. LEFT and RIGHT moves and turns. A
number of keys draw simple shapes. Certain moves can be
erased by double keystrokes. As mentioned, changes and
additions to the program can be made. This is done in the
EDIT mode.
The simplicity and flexibility of this program make it ideal
as a learning vehicle for Color LOGO and more generally for
computer familiarity. The ability to modify the keystroke
functions is particularly valuable.

Much Ado With ADOS
For those of you who are not completely satisfied with
Disk BASIC supplied with your disk controller, there are
alternatives. One is an enhanced version of Disk BASIC
called ADOS from Spectrosystems. ADOS comes on disk
and requires 64K for RAM use or it can be burned into an
EPROM to replace the Disk BASIC ROM now in your
controller. While Spectrosystems does not offer ADOS on
an EPROM. they do furnish you with information on how
to get an EPROM burned if you do not have access to that
capability. If you do not have ADOS burned, it makes a
powerful disk utility just as it comes.
There are several disk operating systems now available if
you believe Radio Shack could have done better with their
version of Disk BASIC While each system has advantages of
its own. A DOS has to be rated very highly. Features include:
repeat and edit of last direct-mode command, automatic
line-number prompts for program entry, lowercase com-
mand entry. DOS command for booting OS-9. one- or
two-column directory with free grans to the screen or the
printer. "COPY <filenamc> TO <drive number>" com-
mand, AE Error override option for COPY and RENAME,
RUNM command to load and execute M L programs. RA M
command for ROM-to-RAM transfers with a ROM com-
mand to return in the EPROM version: SCA N command
lists ASCII file to screen or printer, or it gives START.
END, and EXEC addresses for binary file; a mini-monitor
provides hexadecimal memory examine and change capabil-
ity: PEEP command provides movable window for viewing
memory contents; no known incompatibility with any
commercial software. Also included on the disk is a high
resolution driver with the option of 42. 5 1 . or 64 characters
per line, with lowercase, and a customizing utility to define
your own control-key abbreviations, printer Baud rate, step
rate (6ms-30ms), and the ability to support two double-sided
drives.
Some of these features need a little further discussion. The
down-arrow key. held down while another key is pressed,
functions as a control key. ADOS comes with 22 defined
control keys. There is a maximum of 24 control keys, all of
which may be redefined using the customizing utility. You
are only limited to the 24 keys defined by a total of 116
characters. The contents of the start-up logo may also be
changed. It is suggested that users might want to include
their name in the start-up message to serve as a form of theft
protection for the computer once ADOS has been burned
into an EPROM. The main restriction is the start-up mes-
sage must be limited to a maximum of 88 characters.
Double-sided drives may also be supported in that drive 2
would be defined as the back side of drive and drive 3 as the
back side of drive I . You can also choose to have your disks
formatted with 40 tracks instead of 35, if your drives are
40-track drives. There are some things to consider before
making the decision to go with 40 tracks in an EPROM, i.e..
permanence. First, although you will still be able to read
35-track disks, people with 35-track systems will not be able
to read the last five tracks of your 40-track disks. This
should not cause a problem until your 40-track disk is fairly
lull since the tracks are used starting around the directory
and working outward. Therefore, the top five tracks should
be the last tracks used. If you decide you do need to formal a
35-track disk, a short, five line BASIC program is listed in the
documentation to allow you to format a 35-track disk. A
second consideration is that some disk utilities were de-
signed for a 35-track system and simply will not function
correctly with a 40-track system. Finally, while the COPY
command allows transferring files between disks of different
formats, the BACKUP command will only function cor-
rectly when both disks are formatted the same.
There are two programs provided on the disk that can be
used with other DOSs. BOOT. BAS and RSV. BOOT/ BAS
is a utility that permits you to run any program on a disk by
using the up- and down-arrow keys to select the desired
program. It would be a good idea to put this program on all
of your disks. One of the control keys comes defined as
RUN' BOOT". The other program. RSV, is a high resolu-
tion text screen that gives you 24 lines with either 42. 5 1 . or
64 characters per line. Also, once you are in a Hi-Res.
screen, to get out and back to 32 characters you must hit the
Reset button or type EXEC &HCQ00.
A late update received from Spectrosystems adds to
A DOS'attraction. The main improvements are: I ) the CA T
command now prints the granules taken up by each lilc. 2)
the step rate can be individually customized for each separ-
ate drive. 3) and incompatibility with PBJ's Word-Pak has
been rectified.
Overall. I think ADOSh well worth the price, whether it
is used as a disk utility or burned into an EPROM. I could
not find any software that would not run under A DOS. The
documentation is very clear and the customizing programs
easy to use. One disadvantage of using an EPROM is that
you may not be able to use the high-speed poke, but 1 believe
you would gain more than you would lose.

Countdown To Fun
With Final Countdown
Army generals appear to be. as a general rule, a very
unstable buneh of fellows. At least that's what they appear
to be if you follow their activities in movies and Adventure
games. In these scenarios, generals seem to always be want-
ing lo start World War 111 by firing the first shot at the other
guy. Since activities of this nature are frowned upon by most
people, usually someone is trying to stop him. Peter Sellers
spent the better pari of the movie. "Dr. Strangelove"
attempting to stop a general from starting 'The Big One.'
Now you, with the help of Jarb Software, and your CoCo
can attempt to do the same.
Jarb has released a talking version of their Final Count-
down Adventure. The premise is: A general has started the
countdown on a missile aimed at Moscow. Your mission is
to stop the general before it is too late. Sounds familiar,
doesn't it? However, this Adventure is different in that it
talks to you while you play it. The general yells his vows of
revenge, phones and walkie-talkies give you messages, and
the standard Adventure game responses: "You can't go that
way," "O.K. you have it." etc, are spoken through the TV
speaker as the Adventure progresses. This is the first Adven-
ture game. I know of. to use the capabilities of the Votrax

SC-OI speech synthesizer contained in many of the voice
cartridges currently being sold. Just when I thought non-
graphic Adventure programs were getting dull, along comes
one that talks.
I consider Final Countdown to be of medium difficulty.
Typical of Adventure games, you are required to acquire
and havesomethingtogetsomethingorgosomewhereel.se.
The game is a real challenge.
The game holds your attention, progresses in a logical
manner and is written using Extended BASIC so if you really
gel stuck, you can get help by printing out the listing to find
the key words or the next step. The screen is divided into two
sections: the top shows your current location and status, the
lower shows your last few commands so it is easy to recap
your recent moves and locations - a nice touch. The game
offers different levels of play. The higher the level of play,
the fewer the number of moves you are allowed to have lo
stop the general before the missiles launch. But. the out-
standing feature olihegamc is the use of speech. The capa-
bilities of the Voice-Pak are well-used to add interest and
excitement to the Adventure. On the negative side, the game
contains no graphics. Your imagination must create the
scene. The documentation is sparse. You are left on your
own to find out which commands work and there is no way
to save a game while in play and laler return at the same
point.
To play Final Countdown, your CoCo musl be equipped
with at least 32K Extended basic, and have a Votrax SC-0 1
voice cartridge. I used the Spectrum Projects' Voice-Pak
with the Del Software Translate program included. While
this will limit the number of possible users, those who have
the proper equipment will really enjoy this Adventure.

Nomad: A Rolling

It's sometimes said that the only difference between men
and boys is the size and cost of their toys. Judging from the
electronic gear all over my bedroom, it must be true. Two
computers. TV sets, a stereo system, tape recorders and
numerous radios all get "played with" at one point or
another in addition to the more serious uses they are suited
for. Part of the fun of doing these reviews is in playing with
the new "toys" that CoCo users are likely to find useful. The
vast majority of the hardware I get hold of is mainly
intended for serious applications (you're more likely to use
your printer to write letters than to make dumps of digitized
pictures of Barbara Walters), but here's something that
seems to be devoted solely to fun. Frank Hogg Laboratory's
Nomad is a robot in its simplest form, one which (unlike
things like the Heathkit HERO I or the Androbot B.O.B.)
uses your CoCo as its "brains,"and one which doesn't really
do anything useful. It doesn't try to. All it docs is give you
the chance to play with your own robot. At S250 it's not
exactly a cheap toy (neither is a SI 500 8mm camcorder or a
$ 1 5.000 boat), but then this is hardly in the same league as a
radio-controlled tank.
Nomad is very small, about live inches high, seven inches
wide and eight inches from front to back. It has only two
wheels and a hard plastic foot to keep it balanced. For"eyes"
it has a pair of ultrasonic transducers (which work much like
the sonar focusing on many Polaroid cameras, but come
from a different supplier) sunk deep into a piece of foam
which keeps them separated. A 25-foot telephone-type cord
connects Nomad to its cartridge, which plugs into the CoCo
(for disk systems you will need a Multi-Pak Interface or one
of several adapter cables) and is also connected to an AC
adapter. It doesn't look much like its distant relatives that
you see in the movies, or its closer kin thai help make
dishwashers or pickup trucks, but it is an actual robot.
One of the most often mentioned robot "applications" is
the ability to carry things. Nomad has a small cargo tray on
top, and according to the spec sheet the carrying capacity is
"in excess of two cans of beer." I first wanted to see if Nomad
could carry a video cassette from the TV to my chair, but
remembering that the robot's motors might partially erase
what was on the tape. I instead tried a flashlight: it fell oil
because it was too large for the tray. ( Maybe it could hold a
pair of rabbit ears so that 1 can adjust them with the
joystick.)
Programming Nomad (once you decide to go beyond the
demo programs) isn't difficult at all. The machine language
driver (which works on any CoCo with at least I6K) adds
four new BASIC statements and an intrinsic function to
whatever your version of BASIC" already has. The NOMAD
command tells the robot how far to go, in which direction
(forward or back) and how many degrees to turn (clockwise
or counterclockwise). NOMAD 10,0 would propel the robot
10 inches forward, while NOMAD 0.90 would make Nomad
turn 90 degrees to the right without going anywhere. (Close-
order drill will take a while to figure out, even allowing for
the lack of arms and hands to hold the rifle.) The RANGE
function (it works just like MEM) tells you the distance from
the front ol the robot to the nearest object directly in front,
again in inches. Here's a one-liner that does something really
neat:
10 NOMAD RANGE-10.0:GOTO 10
This tells Nomad to move to a point 10 inches from the
object; if you move your hand around in front of it. the robot
will follow your hand movements (at least front to back). I
should point out that these examples came from a leaflet
that Frank Hogg is presently sending out to the people who
inquire about Nomad.
SPEED and ACCEL change the maximum speed of
movement and rate of acceleration, respectively, that Nomad
uses in its travels. Finally, NCONV lets you alter the conver-
sion factors used for move and turn rate and ranging system
offset and scale. You can then adjust them to match the
characteristics of the robot you have, and you can also
change the factors to correspond to other units of measure-
ment (centimeters and radians instead of inches and degrees,
for instance).
There are several demo programs in BASIC (they require
Extended BASIC to run) that put Nomad through its paces.
The main demo is the most fun of all. because it lets you both
play with the robot and turns it loose (more or less) to run
around on its own. One demo even makes an ultrasonic
image "map" ol the area!
Nomad is based on a precision mechanism that should
work fairly accurately: I'm told that the main bug is the
mechanical slippage in the gears. If you operate the robot on
a carpet (yes. this is one such gadget that does run on the rug)
slippage increases. Judicious use of NCONV will help solve
the problem, though.
Anyway, in the short time that I've had it here for review.
Nomad has been as much fun to play with as anything I've
tried since 1 got my first computer. If you're at all interested
in this sort of thing, I'm sure you'll have a ball with it.

Weight And Speed Give
Good Unit Conversion Practice
Weight and Speed are worksheet makers, designed to give
practice on changing from one weight or speed unit to
another weight or speed unit. These are two separate pro-
grams, each having several subroutines which provide the
conversion exercises for the worksheets. You must have a
printer to use these programs as written.
Both Weight and Speed ate written in identical format. In
fact, they have the same line numbering scheme. The only
difference between the two programs is the number of rou-
tines used for the conversion problems in each program.
Both programs assume you have a printer with 66 lines per
page for the worksheet formal and that you are using the
standard printer Baud rate of the Color Computer. II yours
is different you must adjust your computer or printer. You
are told in the documentation which line keeps track of the
number ol lines used in the worksheet and you may substi-
tute your top of form code if you have one. The one sheet
documentation also explains other important lines you may-
need to know, such as the range of numbers used in the
problems. Both programs are set to use all subroutines, but
by changing the two designed lines you can achieve any

desired combination of worksheet drills.
At the start of each program you are prompted to ready
your printer and continue when ready. Then ENTER the date
and the number ol worksheets and problems per worksheet
you want to a maximum of 60 per sheet. The computer then
prints your worksheets using the following format: the top
line has the worksheet number, a place for your name, and
the dale you entered. Each of the rest of the lines on the
worksheet is an individual problem. The problems consist
of: I) a problem number. 2) the conversion problem state-
ment (forexample."CH ANGE4278 FPS to MPH"). 3) the
problem number with a blank line to enter your calculated
value, and 4) the problem number with the actual answer.
1 he answer key formed on the right side of the sheet may be
given to the student to check his work or if you are a teacher
preparing these problems, to cut off. so that the teacher has
an answer key. Each worksheet is randomized, so is theoret-
ically different.
The following conversion routines are used in the Speed
program: MPH to knots and knots to MPH ( MPH-knots).
MPH to FPS and FPS to MPH (MPH-FPS). In Weight,
the following routines can be found: ounces-grains, ounces-
drams, ounces-pounds, pounds-long tons, pounds-short
tons, pounds-short hundred weight. Other conversion rou-
tines could easily be added.
One thing that bothered me was the author's choice of
"maximum values." Four-digit MPH. for example, seemed
a little impractical to me. but numbers are numbers and they
are meant to be practice d rills. Besides, you can easily put in
your own range of values.
I did find a bug crawling around in the Weight program.
Lack of a "maximum value" to choose from in one routine
created exercises that converted less than one pound to short
tons and caused printer havoc due to overspilling ol that
problem line into the next line. Therefore, if you selected the
maximum of 60 problems per sheet, you no longercame out
with well formatted single-page worksheets. The author has
been notified and the correction has been made for future
shipments.
Weight and Speed may be useful for teachers, students, or
someone interested in becoming more efficient with weight
or speed con\ersions. Extended BASIC is required because
some ECB commands are used: however, the programs
themselves are less than 4K.

Heroes A nd Trolls: A Maze
Math Adventure
Heroes and Trolls, by Cognitive Development Co.. is an
enjoyable 32K Extended Color basic version of the old-
fashioned flashcard for math review. All four math func-
tions (addition, subtraction, multiplication and division) are
covered and three degrees of difficulty are offered. You may
play against the computer or another player. Play may be
handicapped by selecting different math functions and
degrees of difficulty for each player.
The game is billed as an Adventure game but seems to me
to be a maze game with Adventure-type graphics characters
(trolls and dragons). Game play takes place in a Hi-Res
artifact graphics maze. Scoring is shown in the top right ol
the screen while the active player and current math problem
are presented at the top left of the screen. The graphics arc
well done and in such detail that my 10-year-old no-name
TV was not able to do them justice. The sound effects are
simple but effective in adding to the game.
Play proceeds by moving the hero figure through the
maze with the arrow keys to free the subject figures, which
have been turned to stone bv the evil trolls. Invisible trolls
and dragons appear to challenge the hero. The challenge is a
math problem which must be answered correctly in order to
score.
This is a useful game for review of math facts from the
level of two-digit addition on up. but I feel that there are
some changes that could be made to make this a more useful
learning tool. 1 he "random" placement of the game ligures
on each play of the game is not random but follows a
repetitious pattern. This effect of CoCo random number
generation has been covered in THE RAINBOW and it is a
disappointment to find this fault in a game in this price class.
Another problem that should be easy to remedy is the dis-
play of incorrect answers. When a wrong answer is given the
computer shows the correct answer, but for such a short
time that it is hard to see the right answer. I feel a child
should have enough time to examine wrong answers so that
he may find where he went wrong.
Even though the game has these shortcomings. I feel it is a
colorful, enjoyable alternative to old-fashioned flashcards
for practice. It may even catch some children by surprise and
give them some painless instruction.

Coins and A ddition —
An Educational Plus
Coins and Addition are two educational programs for the
Color Computer. Supplied on cassette, these programs
require a I6K Color Computer with Extended BASIC. Coins
is probably intended for use by children ages five to nine
(this is my estimate; the instructions did not state a range).
Addition, according to the author, is intended for use in
elementary and special education classes. Both are described
below.
Coins offers the student a choice of three activities:
1 ) determining the value of a combination of coins
2) combining coins to equal a particular value
3)determining the change resulting from a transaction
Each of these activities can be performed at one of three
levels — easy, medium, or hard.
The display is a graphics screen "billboard." displaying
rows for pennies, nickels, dimes, and quarters. The student
chooses a coin by pressing the key corresponding to the first
letter of the coin's name — 'P' lor penny. 'N' for nickel, etc.

this line does not change to the new line. (You gel 90

5). but is nol supported by the Extended basic. So
beware of RENUMbering RUN-iypc statements.

Unique symbols are placed in each row to indicate the
number of coins selected. Both visual and audio effects
indicate a correct or incorrect response. (If incorrect, the
student must repeat the problem.) At the conclusion of the
activity, the student is shown a "report card." indicating
both the number of questions answered correctly and incor-
rectly, and the percentage of correct responses.
The menus and graphics are simple, but well-done and
attractive. The single-page instructions are complete and
easily read.
Addition presents the student with addition problems at
any of eight selectable levels of difficulty. The first four
levels do not require a "carry" digit; the last four do. The
student initially selects a level of difficulty; the computer
adjusts the level according to the student's responses.
The addition problems are shown on the left half of the
screen in large numerals, using a vertical format — addends
are placed over each other, and the sum is entered below a
horizontal line under the two addends. "Carry"digits, when
required, are entered just as they would be if doing the
problem with pencil and paper.
After the student solves a problem and presses the ENTER
key. the computer checks the student's response. If correct,
the student is given the choice of another problem, or ending
the session. If incorrect, the computer displays the correct
answer on the right half of the screen, and flashes in red the
digits the student added incorrectly.
At the conclusion of the program, the student is given a
detailed summary of his responses. The number of correct
and incorrect responses at each level is shown, as is the
starting level, the final level, and the level of best perform-
ance. If a printer is connected to the computer, the student
may request a printout of his summary.
The two-page instructions are complete and both pro-
grams performed well. My two younger children, ages five
and nine, found them challenging and interesting. (My nine-
year-old wanted to summon her friends to have a neighbor-
hood arithmetic contest; my five-year-old worked diligently
with Coins.) I'd consider these programs a good investment.

Blackjack Royale Version 2.0
Is A Royal Blackjack Trainer
Blackjack Royale. Version 2.0 is a new version of a pro-
gram which 1 reviewed a year ago (August 1983). The pres-
ent program has been made more playable and Faster. This is
probably the best training aid for learning winning tech-
niques of blackjack available for the Color Computer! It isa
very fine program which I enjoyed reviewing.
Blackjack is interesting to the person who likes to gamble.
It is the only game where it is possible to beat the casinos on
a consistent basis. But I only said it is possible to beat them.
Few people can get the advantage over the house. You do
not build multi-million dollar gaudy buildings with winners,
but with losers. Using Blackjack Royaleand one of the good
books on blackjack, you will learn to win. While you may
become a winning player, remember the true mark of a
consistent winner at games of "chance" is that money that is
really needed for life support is never used to play a game.
The only thing that is certain in such games is that you will
also lose on occasion — even at a game wherein you have the
advantage. The long term winner plans for this to happen. If
1 ever find a sure-fire, no-lose method of beating the house
all of the time. 1 would not tell you about it and neither
would anyone else. The statement in the booklet that it is
possible to get a five percent advantage is very misleading.
While there are a very few cases where the advantage is this
high for a second or two. the average advantage is about 1.5
percent for a good counter. Only the very best can get about
1 .8 percent. If I could ever get five percent on the average. I
would quit work, play blackjack all of the time, and get very
rich (if I don"t get shot first).
Several good books were listed in the nice booklet which
comes with the program. To these I would add Wong's
Professional Blackjack, which is probably the best general
book on blackjack.
The most beautiful part of Blackjack Royale is the gra-
phics. My wife and kids liked the funny faces on the face
cards. There is also considerable value in these graphics.
They use only one suit in this game (diamonds) but suits
have no meaning in the modern version of blackjack. The
graphics give the feel of a real card deck. This is what you
need to practice the "card counting" methods which make
you a winner. (Card counting is the name given to the
process of remembering the value of cards played in order to
modify bettingand playing procedures.) This new version ol
Blackjack Royale uses a rapid card generation subprogram
which is a nice change from the original.
In order to get the feel of card counting in a real casino, 1
would suggest one change in the BASIC program. As the
program now exists, the player must hit a key after the hand
to start a new hand. In actual play, the cards are picked upas
soon as possible to allow a new hand to be played. I his
means more money for the house. If you replace Line 740
with the following, the cards will be taken up after a brief
pause:
740 FOR ZZ = I TO 2000: NEXT ZZ
As you get better, lower the 2000 number. You should be
able to keep a correct count down to at least 400 if you arc-
going to win against a last dealer.
Another nice feature of Blackjack Royale is that it allows
you to set any value on a card in your test of card counting
systems. The most common method-counting sets the value
of aces and 10 cards (ten, jack, queen, and king) to minus
one and the low cards (two to six) to plus one as they are
removed from the deck. As the running total gets more
positive, your advantage goes up and the house advantage
goes up as the count goes down. The old version ol this
program used this system as the default but the new version
makes you set in your own system. The use of the -I +1
system is not copyrighted because of the years of use in
mathematics literature. The authors could have used it in
their program if they wished to.
There were several minor mistakes (bugs) in the earlier
edition of this program. These were pointed out in the first
review. I guess the author did not read it. because only one of
them was fixed in this edition.
The most serious error in the first program was the fact
that the count did not reset when the cards were shuffled.
This has been fixed and it works fine. The input of data into
the bet or the card count value still must be done with care or
the computer will misread it.
There are three blackjack rules which are used incorrectly
in both versions of this program. The surrender option is
still incorrect. Do not use this option. A surrender is sup-
posed to have both the dealer and the player get a new hand
alter half of the player's money is taken. This program forces
the player to get new cards while the dealer keeps his cards.
Other rules which have errors are the resplit of pairs which
the computer cheats at and the double alter splitting pairs
which doubles both of the hands instead of only one.
Blackjack Royale. Version 2.0 is an excellent program,
and it should be bought by anyone who wishes to learn to
play winning blackjack.

Compression Utility —
Three Programs Rolled
Into One
This software package contains three utilities that all
work toward compressing, decompressing or relocating
graphics screen data.
To get an idea of what compression is all about, try to
imagine a graphics screen from one of your favorite space
arcade games. There will be the black space background
with many little white dots for stars and a few spaceships.
Many of the adjoining bytes that makeup the picture will be
identical, such as the byte value zero that will produce a
black line eight pixels across for the space background. By
checking and cataloging for repetitive byte values, com-
pressing a picture like this could result in cutting the
memory required to store it in RAM or disk to about 30
percent of the original space. In other words, a PMODE4
Hi-Res screen normally uses 6144 bytes, but when com-
pressed will only take up approximately 2100 bytes.
Not all screens will save this much memory however. The
more complex the picture, the less memory will be saved

through compression, but on an average you can expect a 15
percent to 60 percent reduction factor.
The first program is called Graphic Compression Utility
or GCU (not to be confused with a program with the same
initials from Computi/e)and is menu-driven I or easy opera-
tion. It allows you to load and view a Hi-Res screen from
disk and choose to compress it or not. If you do compress it.
a new disk file under the same name will besa\ed but with a
special extension for identification.
After the compression has been completed (about a 10-

the original screen was, how many it has been compressed
down to and how many bytes have been saved.
Some graphics screens have such complex designs that
not much if any memory savings will result through com-
pression and the program will tell you so.
The user has the choice of determining w hat portion of the
graphics screen is to be compressed by using a simple line
cursor to delimit your screen. This is ideal if you want to use
the upper screen for pictures and the lower half for text such
as in Adventure games.
The second program in this package is Graphic Decom-
pression Utility (GDU) that as its name implies, takes com-
pressed graphics files from anywhere in memory and blows
them back up to their original size with no loss of detail. This
program is a module called by hasic's USR command or
through a machine language program. This module is relo-
catable and takes up only 300 bytes of overhead, which is
really insignificant when you add up all the graphics bytes it
will save by compression.
The third program is called Graphic Relocation Utility
(GRU) and it loads in picture files from disk, tells you what
address they start at and prompts you for a new start loca-
tion. It relocates itself before you can take your finger off the
ENTER key and is ready to do another.
Only PMODE4 is supported but i hat's no problem since
this graphics mode is now the standard for CoCo graphics
when employed with artifact colors. The program is not
copy protected and comes on disk, but once the graphics
have been compressed they can be saved to and loaded from
tape (but no instructions are given for doing this).
A demo program is included to supplement the documen-
tation, which consists of five pages of instructions. Instruc-
tions are also available from within the program itself that
will let you jump in right away.
The documentation is sufficient but does not take the user
by the hand through all the aspects like utility programs
should. A good working knowledge of BASIC programming.
USR calls and the CoCo memory map are required to really
get the most out of the program with a minimum of learning
overhead time. Novice programmers may get a little snowed
by not fully understanding what is going on from the start,
but will catch on before long.
I would recommend this program to anyone who does a
lot of graphics programming and wants to achieve some
remarkable results using an absolute minimum of memory
for graphics data storage.

THE RAINBOW December 1984
Software Review!
ZGZ\ Software Review!
Letting CoCo Do Two Things
At Once With Super Spooler
Well, what's this on my table? It's a spooler called Super
Spooler from THE RAINBOW to review. The documentation
seems really complete. It is tape and disk versions — 32K
and 64K (although they say it will work with any size
memory).
Do you know what a spooler is'.' A spooler, in this case a
print spooler, is a device which intercepts characters to be
printed and stores them in a buffer. Then, one character at a
time, it prints out a character to the printer, giving you
control of the computer at the same time. In other words,
you can be printing one thing, and using the computer at the
same time. This is why any spooler would be a valuable
addition to a software library (if you own a printer of
course!). Think about it — writing a program while your
mailing list or a letter is being printed at the same time.
I turn on my trusty 32K CoCo. For the 32K version, you
just clear some memory. LOADM "SS32K/B1N" and
EXEC. It worked! Now I can load in my own program and
LUST. Buffer Overflow! One drawback is that 32K sure
can't hold a lot. However. Tandar Software does recom-
mend that you use a 64K Color Computer, and the docu-
mentation says I can expand the buffer to make it bigger, but
it doesn't sav how. Well. I sure am glad I also have a 64K
CoCo.
The 64K version works nicely and has a large print buffer.
The instructions say I can use this with Telewriier-64. as well
as other word processors, and it works fine with Disk Scrip-
sit. It really prints out smoothly on the DMP-400 (a Radio
Shack printer), but the good thing is they say that it can
work on all printers too! The manual also contains a com-
patability chart, a quick reference sheet, a memory map and
for $5 extra, you can get the fully commented assembler
source code. I think this is a great idea for programmers who
wish to learn how a spooler works.
They also have a return policy which is very good. Just
send it back and a new copy will be shipped.
A registration sheet is also included in this package. Once
you register your copy of Super Spooler, you will receive
catalogs and news about other Tandar products. Also, you
can get my favorite seven letter word — support!
Super Spooler is a fine utility for anyone with a printer
and 64K. Although the company states that the program
will work with all memory sizes. 32K (or less) owners should
think twice before buying it because of the small buffer
capacity. Congratulations to Tandar Software on a fine
offering!

Androne — A Fun
Way To Zap Bugs
As all of us who have tried to write our own programs on
the CoCo know, there are dozens of tiny bugs hiding in our
16 or 64K of RAM. They sit there waiting and then pop out
at you. hitting you with "SN Error." How often we have
wished for a handy phascr to just zap them out of our lives.
Being the thoughtful company that it is. Radio Shack has
given us the chance to do just that with its new program
pack. Androne.
In the game, you are Androne. the terminator, searching
each byte of memory for "data bugs." Be warned that data
bugs attack Androne whenever they see him. Each attack
drains Androne of energy. Go down to zero energy, and it's
all over. There are power units at each level to recharge
yourself so you have at least a fighting chance.
The display shows the room you are in as well as your line
of sight in the direction you are facing. The room graphics
arc 3-D and are similar to Dungeons of Daggorath. Data
bugs appear as eliptical laces that zoom in and out as they
attack you. I really like the effect as you get hit by data bugs.
As they hit you, the whole world shakes with their powerful
blow. Power units are hour-glass shaped. The screen also
shows a mini map of your level, a power gauge, a direction
indicator, and your score. The power gauge shows how
much power you have left before the end.
The game is played with the left joystick. It controls your
movement through the maze as well as your shooting. To
shoot, you push and hold the lire button while using the
stick to position cross hairs on the data bugs. I he maze has
"pressure" steps that dissappear as you step on them. This
makes finding your way around much easier as you can
always tell if you have been there before. Points arc awarded
for killing data bugs, stepping on steps, and getting power
units. The point values go up as the level of the game goes
up.
I found Androne to be quickly understood but not easily
mastered. Out of the seven levels, the highest 1 could play
was level four. The joystick is very responsive: almost too
much at times. I found that, like Skeei, you must lead your
targets. The only flaw with the controls is that you cannot
jump backward. Instead, you must turn around and then
move.
Androne is an enjoyable game for those of us who don't
often make the "Scoreboard" section in rainbow. The
arcade masters should try it first to see if it is too easy for
them. Dr. Megabyte prescribes it as an excellent game for
the new CoCo owner. It gives a good look at the graphics
and sound that the CoCo can do without being too hard to
understand. It's also not so easy that playing it a few times
will make it boring. The doctor takes his hat off to Mr.
Arnstein (the author) and to Tandy for giving us a mid-level
game of high quality. If you arc like me. and are not one of
the arcade masters, you will like this one.

Fly Away With Kay,
The Spelling Bee
Crystal Software has introduced an educational word
game of the highest caliber. Kay, the Spelling Bee. is a high
resolution animated graphics word game lor one or two
players which requires I6K Extended BASIC. It comes with a
file of 260 words covering two skill levels and three game
variations. It is also possible to create additional word files
which can be saved to tape.
The object of the game is to help a cute little bee named
Kay find the letters that make up the word hidden in a
flower. Player(s) input letters using the keyboard. Each
correct guess results in the letter appearing in all applicable
blank spaces. Each incorrect guess fills one of eight beehives
with the wrong letter. Your reward for finding the right
word is a musical celebration and a smiling llower. Once a
word is found, it will not be repeated during the session. If
alter eight incorrect guesses, you cannot figure out the word,
the correct word is displayed on the screen.
After Cl.OA Ding and RUNning, the game menu appears.
Make sure the PLAY button is depressed because the word
file will not be loaded unless needed. Game optional is a one
player game in which the computer selects a word at random
and challenges the player to guess the word. Game option #2
is a two players against the computer format. Players take
turns trying to be the first to discover the word. A scoring
sNstem makes this option highly competitive. Option #3
allows players to take turns entering a word for the other
player to solve. The same scoring as in option #2 applies.
One of the really good things about this game is that with
the ability to create word liles the limits are endless.
Although advertised for ages seven to adult. I found that
seven-year-olds might have trouble with the existing word
file. The ability to create a file more suited to their level is
most welcomed, since the youngster should have no trouble
with the mechanics of playing the game. Creating a word file
is one of the options in the main menu.
I have nothing but praise for Crystal Software's effort to
bring quality educational programs to the marketplace.
Spelling Bee is an excellent word game for use at home or in
school. The animated graphics are very well done and will
bring delight to the most critical of players. This is a game
thai should be part of every user's educational software
library.

Preparing Your Income Tax
Form With TAXAID
Video Reverser Is Easy
To Install
The preparation of our annual income tax returns is a
form of involuntary servitude not abolished with the other
slavery in 1865. A program which would help us keep our
accounts and papers straight lor this ordeal would greatly
help. TAXAID is not that program.
It would be unfair to focus on the mere formal shortcom-
ings of this package, except that they are so symptomatic.
The author cannot spell ("royality" and "rccieve" are two
samples, one of which turns up on the printouts), and the
layout of his text on the screen is abysmally sloven. What
TAXAID amounts to is a series of basic programs or
modules which establish three ".DAI" files from which
printouts are made. Each of the modules must be accessed
by the user from the directory (in the disk version): there is
no attempt at a menu, although each program ends by
re-invoking the root module as if a menu were resident there.
TAX AID's purpose is to prepare and print federal sche-
dules A. B. C, E. F. G and child and dependent care for
inclusion with your 1040: it also calculates data for Form
1040 and prints it by line number. You are required to
compute such things as casualty loss (here spelled "casual-
ity") and capital gains beforehand. Did you think that was
what the computer was for? Well, you were wrong.
Even the printouts are formatted in a casual manner at
best, user input appearing substantially where chance places
it. And most of the modules won't run at all if you have no
printer on line.
And it is all s/ow, and slower when you have to hit BR1 \k
and readjust the printer between forms — a matter which
could have been handled from inside the program with
perfect ease.
Given all these faults, it seemed pointless to this reviewer
to check up on the simple floating-point arithmetic which is
the most the program is expected to do.
I he most attractive feature of TAXAID is its price — but
you get what you pay for. after all.

When I first saw the CoCo back in 1980, 1 couldn't figure
out why the text display was done in black letters on a green
background with a black border. Quite a few CoCo users
have. I gathered, wanted to change this. Sometimes it's done
in software, sometimes in hardware. The Dynamic Electron-
ics Video Reverser is a good example of the hardware
approach.
The Video Reverser is simply a single chip that connects
to the 6847 video generator in the CoCo. One pin of the 6847
controls whether normal or inverse video is used: the video
Reverser feeds it exactly the opposite of the signal coming
from the microprocessor. One of the three available models
does only that; the other two have a switch that selects
normal CoCo operation, inverted characters or a third
mode that displays all characters including lowercase as
green letters on a dark background. The Video Reverser
works on any CoCo. including the TDP System 100: 1
expect it will also work on the Dragon and the MC-10.
though I haven't tried it. On the MC-IOand a very few early
CoCos you will have to unsolder the 6847 from the board.
As I said, there are three different versions of the Video
Reverser. The VR-I. which is intended for the D and E
board CoCos, has four leads coming out of the chip with
liny eyelets on the ends. You have to unplug the 6847. bend
one of its pins up. attach one lead to that pin and the others
to three other pins, then plug the 6847 back in. This is a very
ticklish job. and when I tried to install our first sample one of
the eyelets broke off. On the NC board and the CoCo 2 you
can use the VR-I M. which isa module that plugs in between
the 6847 and the main board. This version is slightly more
expensive, but may save you some time and aggravation. 1
don't think it will work well on the D or E board models
because of the RFI shield over the 6847: the module raises
the chip about '//'. The VR-2 is the same as the IM. but
doesn't have the switch and. therefore, inverts at all times.
Before you take the plunge and put in something like this,
you should know that the CoCo's text display when inverted
in this manner consists of light green characters on a dark
green (not black) background. This is because the color
"difference" signals that tell the encoder to color the active
area green stay on whether the point in question is light or
dark. In normal CoCo operation this only makes the charac-
ters a bit fuzzy in many cases, but when you invert the text
display you get a rather odd-looking screen. This is true no
matter how you invert the display, and is not the fault of the
Video Reverser. One thing 1 don't like about the product is
that the IC'stype number has been blacked out. When I buy
something I feel 1 have a right to know what's in it.
II you think reversed video would be a worthwhile
improvement, the Dynamic Video Reverser is a good way to
get the job done. I'd suggest the deluxe VR-I series over the
VR-2 simply because ol the added flexibility.

SP-2: Improved Serial Interface
At A Good Price
The SP-2 Serial Interface does nol have anything to do
with Rice Krispies or Captain Crunch.
What it does do is allow your CoCo and the popular
Epson printers to "shake hands" and get some work done,
lather than just sitting there and staring at each other.
Your CoCo feeds information to a printer one bit at a
time. Most printers. Including Epson, are designed to lake
information several bits at a time, in parallel fashion. There-
fore, you need something which can translate for your
CoCo, and that's where the SP-2 comes in.
An improved version of the SP- 1 was reviewed in the June
1983 issue of THE RAINBOW. The SP-2 is designed for the
MX-80. MX- 1 00, FX-80 and RX-80, and also works with
Graftrax-80and Graftrax-Plus( MX-80 options). It features
an increased range of Baud rates (300-9600 for basic. 19200
for machine language) and an improved oscillator requiring
no adjustments.
The SP-2 allows you to access all the type fonts and
graphics modes that your Epson printer has and will proba-
bly decrease the time you spend waiting on it to finish
printing. A large number of peripherals accept data at a
speed of 600 Baud, the rate at which Epson printers are set at
power on. However, you can speed up your operation con-
siderably by increasing the Baud rate. How much? A full
page on the MX-80 takes approximately three minutes to

print at 600 Baud, with each line of print taking about two
seconds to feed into the printer. A full page at 9600 Baud
takes only I '/; minutes, or half the time. On a 1 0-page paper,
form letters, mailing lists or screen dumps, you better believe
that makes a lot of difference! Apparently not all CoCoscan
operate at 9600 Baud, but anything above 600 will make
things go a lot faster. The selectable range of the SP-2 allows
you to choose the fastest speed suitable to your CoCo and
your particular application.
The illustrated instructions are among the clearest and
most complete I have seen for hardware. If you follow them
step by step, you should encounter no problems. All you
have to do for most CoCos is open the printer, carefully plug
in the board, tighten the screws, set one DIP switch, close
the printer, and POKE as necessary. If you happen to have
an early CoCo model which uses 7-bit ASCII code, all you
have to do is Hip one other DIP switch and you're set. If you
don't know which yours is. EXEC 41 175. If the screen says
"COLOR BASIC 1.0." you've got a 7-bit machine.
The SP-2 cable is permanently attached to the board (no
connector) but that's no problem for most of us. You may
wish to invest an extra five dollars lor an external switch.
This will allow you to use the printer's parallel port without
removing the interlace board, as well as permitting you to
change Baud rates without opening the printer. Once the
switch is set the Baud rate stays the same, though if you are
using anything other than 600 Baud, you must POKE the
right value into the computer each time you turn it on. since
the printer powers up at 600 Baud.
Detailed technical information and a parts list are includ-
ed. The SP-2 will work with no parity bit and at least one
stop bit. a parity bit and at least two stop bits, or even with a
parity bit and only one stop bit. For S 10 extra, you can buy a
true RS-232 version.
Two years ago 1 paid about S80 for an MX-80 interface
that had very limited Baud rates and did not permit me to
use the "dot graphics" and thus screen dumps — 1 would
have had to shell out another $70 for that privilege. In
addition, I had to provide my own cable — which meant
about $20 more. The SP-2 provides its own cable, permits a
full Baud range and allows lull access to all printer graphics
for half the price. Check it out — 1 think you'll agree it's a
good deal.

Christmas Quiz — Excellent,

II you want to do some early Christmas shopping this

later.
The good folks at Quality Christian Software are out to
prove the first part of their name is no quirk. Christmas Qui:
is an excellent religious learning tool, as are the other
members of the QCS family of programs. It is written in
basic and can be modified if desired, but it is just fine as it is.
The documentation is one printed sheet, but that is all you
need, as the instructions on the program menus are more
than sufficient to meet the operator's needs.
This program has one goal of "keeping Jesus the central
locus of Christmas." That goal is achieved through a series
of questions designed to expose the biblical view ol Christ-
mas, as opposed to legendary and folk views of the nativity.
1 saw it not only as a tool for Sunday school, family study
or Bible qui/ teams, but a place for adult study groups to
kick off some mighty important and informative fellowship
sessions.
As an example, one question asks the number of wise men
who came to visit the Lord. The number of Magi is ne\er
stated in the Bible (although three gifts are mentioned) so
the question brings you to that point with scriptural refer-

The program could be used for competition or for drill. It
returns a report of the number ol questions answered cor-

A Fun,
Monster-Filled Adventure
Middle Kingdom is a recent addition to the catalog of the
good folks of Computerware in Encinitas. Calif. This is a
high resolution Adventure game with the flavor of "Dun-
geons and Dragons." The object of the game is to recover
three magic rings lost in the kingdom and return them to the
sanctuary. Success is rewarded with the crown of the king-
dom and failure is met with death. Obstacles to getting the
rings are rather interesting creatures like orges, dwarfs,
lizardmen, trolls, and goblins.
The graphics of Middle Kingdom are exceptional. The
title screen displays the villians. weapons, and magical
spells. There are three different skill levels and you are given
a choice of being a magician, wizard, or merchant. You
begin the Adventure in the sanctuary and can travel to the
pyramid, catacombs, or temple to search for rings and trea-
sure. The instructions tell you that the catacombs arc more
dangerous, but more rewarding. When you are in the sanc-
tuary, an audible buzz is heard to alert you to where you arc.
Movement is accomplished by using the arrow keys. In
setting up the game at the beginning, you have a choice of
slow, medium, or fast movement. Slow is suggested for
beginners, but fast is much more interesting. Keyboard
response is excellent!
Four weapons or spells are given to you at the beginning
of the game. Other weapons and spells can be found in the
graphics mazes. Weapons include such things as swords,
daggers, axe, mace, long bow, and trident. Spells include
lightning, petrifying light, fireballs, and stun spells. You are
only allowed seven weapons or spells at a time, and when
you find more than seven, you must choose one to drop.
This is easy — the spells must be used quickly or they loose
their power. Certain weapons work better on certain crea-
tures, but you'll have to discover those on your own!
All action lakes place on one screen. The top portion of
the screen tells you your location, points accumulated, and
time expired. The score and time have no relation to the
success or failure of the game, but it is a nice feature. The
second portion of the screen is where the action takes place.
The maze structure takes you through the middle kingdom.
The bottom portion of the screen lists your weapons which
are controlled by number keys one through seven. Action
summaries are given next on the screen. This information
details the fighting that takes place and the treasures that
you find. When you meet a creature, you automatically
strike the first blow, and the result is recorded. Then the
creature does its damage. The results of each conflict are
tabulated at the bottom of the screen. You earn experience
credits for each successful conflict, and your strength is
updated after each action takes place. You begin this game
with zero experience and strength from 1 50 to 250. depend-
ing on the skill level you chose at the beginning of the game.
When your strength reaches zero, you die and the kingdom
is lost.
Middle Kingdom is a well-developed software game. The
game is well written, the graphics are tremendous, and the
game operation is smooth as silk. I was able to conquer the
middle kingdom on my second try (level one) and have won
224 THE RAINBOW December 1984
playing level three. The language is interesting and very
creative. I especially liked the phrase. "You've been hit on
the head . . . but no damage done!"
This is not a difficult game, and can be played by children
as well as adults and I think this is very important for the
consumer to know. A different kingdom is set up every time
you play the game, so once you conquer the game, you can
still enjoy playing it again and again. The game is winnable.
and I welcome games for the Color Computer where the
player can win. I have a concern about continually playing
games where you always die and the only victory is how
many points you get before you perish.
The only problem I see with Middle Kingdom is that it is a
random-type game. You are given no hint or clue where
creatures are hidden. Thus, there is no way you can avoid the
monsters. Once you come in contact with them, you must
fight, even if your strength value is almost gone. Because of
this, the success or failure ol the game is somewhat left up to
chance. The effects of the weapons used in battle are also
randomized.
I enjoyed Middle Kingdom. My nine-year-old son. Jeff,
loves the game. I think he likes to win sometimes, but then.

Musica 2 — Creating Beautiful
Music With Your CoCo
Ah. music. I'm one of those folks who enjoy listening to
music, but have no talent playing a musical instrument. It's
not that 1 haven't tried I did my mandatory two years of
piano lessons before my parents' patience and pocketbook
gave up. I can still remember where middle C is. but not
much more.
I was even in my high school marching band, attempting
to play clarinet. I don't remember anything about the cla-
rinet except that there was a rumor circulating around that
playing a reed instrument made you a better kisser.
For you musical composers, let the forcmentioned serve
as a warning. This is being reviewed by a novice. A novice
who had fun.
My first exposure to the musical capabilities of my CoCo
was when I learned about the PLA Y and SOUND com-
mands while fumbling through the instruction manuals
included with the computer.
After playing Three Blind Mice and inserting some simple
tunes into a few of the educational programs 1 wrote, my
interest in the musical capabilities ol the CoCo was at a low
level.
My embers of curiosity, regarding the musical capabilities
of my gray buddy, were rekindled when I obtained the
Music Library 100. This program consisted of a bunch of
songs generated using the Musica 2 Music Synthesizer pro-
gram from Speech Systems.
The music generated by by Music Library 100 was unlike
anything I'd ever heard from my CoCo. Up to four voices
are played at one time. And although the results sound like
they're played through a Moog Synthesizer, the sounds were
quite pleasant.
Music Library 100 only allows you to play songs which
someone else had generated using Musica or Musica 2.
Would it be possible for my tin ear to compose palatable
tunes? Anxious to find out, Mm;Va2wasadded to my stack
of 5!/i-inch disks.
Musica 2 also allows you to play music previously created
using Musica or Musica 2. Eight songs are included to get
you started: however, the real "meat" of the program is the
ability to write your own compositions.
Entering music is quite easy as all notes are entered and
displayed on standard musical treble and bass staffs. The
position of each note is selected by moving a cursor up and
down with the arrow keys or a joystick.
The music you arc working on can be played at any time
so you you can hear your masterpiece and if you wish, edit
your creation. Insert, Delete and Block move commands are
available just like a word processor.
Up to four voices (chords in four-part harmony) can be
played at one time. Each voice can have its own timbre (such
as the sound ol a violin, flute, or oboe) and the assignment to
each voice can be varied during the composition.
The tempo of the music can be varied during the composi-
tion and advanced users can play all sorts of aural tricks
using a wave form synthesis option.
The tonal quality of your composition can be enhanced by
using a remote speaker if your television can accomodate
one. Most televisions called into service as CoCo monitors
have poor speakers. For the ultimate sound reproduction.
Speech Systems sells an attachment which plugs into the
ROM port ol the Color Computer and directs the output of
Musica 2 to an external stereo system. The Stereo Pak also
separates the signals into treble and bass and creates an
effect which is most impressive.
When your masterpiece is finished or you'd like to stop,
the composition can be saved to disk or tape using standard
format files. You can also assess and play your composition
from a BASIC program.
For posterity, or if you want to submit your composition
to Carly Simon and make your next fortune, you can print
out your score using a dot matrix printer. The program will
print out the notes on the standard musical bass and treble
staffs. While this is a very nice option, if you have a long
composition, be prepared for a long wait, because the print-
out is slow.
How does Musica 2 make all those great sounds? Here is
Speech Systems' explanation:
Musica 2 generates a stream of numbers that the Color
Computer converts to voltages through the sound port (6-
bit digital-to-analog con verier). By varying the numbers and
thus the voltages at the appropriate rate, a tone is produced
through the TV speaker. Pitch is varied by skipping a certain
numbers of values. This method of varying pitch makes it
possible to produce more than one note at once.
How good is the music you can produce using Musica 2''.
How good is a Steinway? The answer varies with how much
talent you have and how much time you arc willing to invest.
The tools for creating your masterpiece are there - you just
need to apply the time, energy and talent.
II you have a 32K minimum Extended BASK CoCo and
an urge to create beautiful music or even MTV rock, Musica
2 may be for you.

Happy Birthday, Mr. Gift
Is A Gift For Young Children
When children first learn to read, vowel discrimination
and pronunciation are some of the more difficult tasks they
need to accomplish. When should they use a short sound
and when is a long sound appropriate? It is very easy to mix
up words like pin and pen. There are rules to be learned.
Happy Birthday, Mr. Gift is an attempt by Teksym Corpo-
ration to reinforce the vowel rules for reading.
After the program is CLOADMeil. the child is asked to
type his her name. At this time a personalized invitation to
Mr. Gilt's birthday party appears on the screen and a voice
reads it to the child. The audio capabilities of the CoCo are
put to full use with this program. The child can hear all
descriptions and instructions. There are five levels from
which to choose, ranging from Level I. which allows the
child to answer with no time limit, to Level 5. which gives the
user five seconds to answer.
During the game portion of the program, a picture
appears with two words next to it. For example, the child is
told that Uncle Hill is giving Mr. Gift a present (the picture).
The child is asked to identify the gift by choosing I ) tee or
2) tic. The user can enter his choice in one of two ways. He
can simply press the number key or select the appropriate

As I sat down and played this game. I couldn't believe how
bored I was. The game seemed to move so slowly and the
taped voice became more and more annoying to me. Realiz-
ing that this program was meant for beginning readers (K-
2), I went in search of a first graderand Kenny, age six. came
to my rescue. He spent quite a bit of time with Mr. Gift and
he made quite a few mistakes the first time he used the
program. The most confusing part for him was in the use of
the arrows to answer. This is explained in the documenta-
tion as a way for children who don't know numbers to
answer the questions. Once he was able to straighten this
part out. he went on to enjoy the game. As with most young
children, he really liked being able to use the computer.
After watching and listening to Kenny. I really had to
reassess my opinion. I now find that it is perfectly suited to
the age group lor which it was written. Kenny was able to use
the program without adult supervision or assistance. He
used the program repeatedly and said that it wasn't too hard
or too easy for him. It was obvious that he enjoyed playing.
Its biggest Haw is that it only offers l() problems. Keeping in
mind the intended user. Happy Birthday. Mr. Gift is a useful
supplement for a child who is learning to read.

Develop Your Own Adventure
With Adventure Generator
By Jorge Mir
I have always enjoyed computer Adventures. As a child I
had a vivid imagination and I seem to have retained a good
portion of it because I can really get engulfed while solving
Adventures on my CoCo.
You might recall the July and August 1982 issues of THE
RAINBOW where my articles on Adventure writing were
published. The August issue contained an Adventure driver
program to aid in developing them, however, it required
some programming knowledge to develop your own Adven-
tures since it only provided the logical steps needed to pro-
cess the Adventurer's commands.
Well, CoCo owners now have an Adventure generator
program which will allow the development of Adventures
without any programming knowledge.
The Spectrum Projects' Adventure Generator (called
SAG) allows you to develop your own Adventures and
compiles them in machine language so that they can be
played at a much higher speed as compared to basic Adven-
tures. Not only that, but after you have created your Adven-
ture and are ready to save it, SAG gives you the choice of
creating a regular silent Adventure or one that talks! Yes.
that's correct. Adventures created with SA G can be played
with the Spectrum Projects' Voice Pak!
Having the ability to create talking Adventures should
prove to be quite interesting since it opens up a new avenue
to explore for all of us engaged in Adventure writing.
SA G requires a disk system with at least 32K of memory
(64K for talking Adventures) and it comes with a series of
programs to allow maximum usage of the CoCo's memory
while developing your Adventure. These programs are
linked to each other through the use of menus, making it
simple for the user to follow the various steps necessary as
the Adventure is being generated.
The system's programs are a series of editors allowing you
to enter the various verbs, rooms, objects, flags and mes-
sages necessary to process the commands entered by the
Adventurer as the game is being solved.
As with any CoCo program, there are some limitations.
SAG contains the following limits for each item:

Rooms

Program

8,600
The maximum number of bytes for program lines in a
talking Adventure is 7,680. Also, both versions can have up
to 255 flags to test conditions throughout the game. This
gives us a lot of space for developing some pretty interesting
Adventures.
As each section of the Adventure is being developed, you
are shown the number of items entered and the number of
bytes available in each section. This is quite helpful in judg-
ing how much room there is left for additional data.
The various editors allow you to entei each item giving
you the ability to further edit or delete them at any stage of
development. Each editor allows you to save data independ-
ently of other editors. This is an excellent feature since it
allows you to start with a very short Adventure and continue
to expand it as you go along.
As you enter each object, you are prompted for additional
information: message number if the object is examined,
whether the item can be readily seen or not. whether it can be
"gotten" or not and the room number where the object starts
in the game. As you enter the room data, you are also
prompted for the obvious exits out of the room (north,
south, east, west, up or down).
The Flag editor is simple and straightforward, but you
should take some care in designing your flags if you are a
beginner in Adventure writing. The simplest way to explain
what a flag does is that it helps you to test conditions using a
minimum of computer memory. Flags can be set to equal
either a numeric one or a numeric zero. A one indicates the
flag is set and a zero indicates it is not set. When designing
flags. 1 always describe the flag so that if it is set to one it it
means "yes" and if it is reset to zero it means "no." For
example, if a Hag description is "Door is unlocked" and the
flag has a value of one then it means, "yes, door is unlocked"
otherwise it would mean it is not unlocked.
When reading about the limitations of the program, you
may have wondered if 700 lines for the Adventure program
would be sufficient for some of the more complex Adven-

tures. Well, 1 wouldn't worry too much about it. The sys-
tem's program line editor follows a unique language espe-
cially designed to conserve memory and, yet, allow you
maximum flexibility when designing your Adventure.
When you first read the manual that comes along with the
system, it seems a little hard to grasp how this language
works. But, when you get to the line editor program, the
screen is full of information so that you don't have to refer
back to the manual when developing your program. This is a
big plus.
Each program line entered by the Adventure writer is to
test a condition. If that condition is matched, then the
outcome, as entered by the writer, will take place. Let's
assume your Adventure has a door that can only be opened
if the player has a key in inventory. Logically, your Adven-
ture might look like this:
IF verb is number 10 (unlock), and object is number 5
(door) and you are in room number 2 (in front of a house)
and object number 8 (key) is in inventory, THEN set flag
number 6 (door is unlocked) and print message number 20
(the door is now unlocked).
To accomplish the above, you will enter the following
program line with the language editor: V10N5R2I8=S6P20.
To the left of the equal sign is the condition which, when
matched, will result in the outcome shown to the right of the
equal sign. I am sure you can now appreciate how much you
can really accomplish in a single program line, so you can
imagine what you can do with 700 of them!
Once you have entered all your verbs, objects, rooms,
flags, messages and have completed your program lines,
there are two compilations to be made. First, you have to
compile the language lines (one of the selections from the
main menu in the language editor program). Next, you have
to compile the entire Adventure (a choice from the main
menu) at which time you have your choice as to whether you
want the Adventure to be silent or a talking one. You will
also have to decide other things, such as maximum number
of items the player is allowed to carry in inventory, the room
number where you want the Adventure to start, etc. You will
always be prompted for information required by the system,
so there is no need to refer back to the manual. Thai's what I
call a "user friendly" system (some people may call it "idiot
proof," with all due respect to the user).
Not only do you have a choice as to whether your Adven-
ture should be silent or talkative, but you can recompile a
silent Adventure into a talkative one or vice versa without
the need to re-enter any of the data. That's another big plus.
When developing a talking Adventure, you need to be in
the all RAM mode, using 64K and, of course, be familiar
with the use of the Spectrum Projects' Voice Pak. A short
subroutine is included with the system so you can switch the
computer to the all RAM mode.

A programmer usually tries to place him/ herself in the
user's place when designing systems so that such systems will
meet as many requirements imposed by the user as possible.
Since it is impossible to satisfy everyone, users can usually
readily point out, from their perspective, those features
which are missing in the system. Following are the faults I
found when using the system.
The condition/ result combination (if such conditions are
met, then do the following), could have been expanded to
allow an ELSE result. Using the above illustration when
trying to unlock a door, it would have been nice if the user
could expand the step so that if the condition is not met (for
example, if the key was not in inventory), then another set of
program lines would execute, such as printing a message like
"you need a key to unlock the door." You can work around
this apparent deficiency by adding a next step to test if the
door is still locked (without testing to see if the key is in
inventory) and then printing the above message if it is not in
inventory. Nevertheless, it would have been nice to have the
"IF- THEN-ELSE" capability.
Another inconvenience is the fact that all objects or nouns
must contain at least four letters. This is a problem if you use
words such as DOG, CAT. LOG. KEY, ICE, TIE, POT,
CU P. etc. After you describe the object, you have to enter a
four-letter abbreviation and that is where the inconvenience
pops up. You can get around it by changing your objects
such as calling a KEY a BRASSKEY so the abbreviation
can be BRAS, or calling the ICE an ICECUBE, with the
ICEC abbreviation for it. Nevertheless, it would be much
nicer if less than four letters could be used as abbreviations
for each object. I have communicated this deficiency to
Spectrum Projects to see if it can be corrected and they have
promised to look into it.
Please keep in mind that this program is not designed to
teach you how to write Adventures. It is simply a great
program to allow you to develop Adventures once you have
formulated them in your mind or on paper. If you try to
develop an Adventure and think itoutasyouenterall of the
data using the SA G system, you are bound to become very
discouraged since things will not take place as you envision
them. You must first design the Adventure, preferably on
paper, indicating all of the facts to be encountered by the
adventurer and all of the conditions to be tested along with
the related outcomes. After all that is done, then run the
SAG system to get all the programming accomplished.
Since most people just like to jump into things, I am sure
many who will buy this system will not follow the above
advice. Well, SAG takes care of this problem nicely, since
you can always go back and edit any of the data previously
entered and recompile the Adventure again. It would just be
a lot easier and less time consuming to complete the Adven-
ture if it is well thought out before you start using the SAG
system.
Overall, I think this is a great system for those interested
in writing Adventures. It sure eliminates a lot of time
involved in developing them and allows the non-programmer
to develop some very interesting Adventures since no pro-
gramming knowledge is required.
Try SAG, you'll like it!

Colorgrade —
An Educational Application
Program
By T. Gray
Choosing a gradebook is largely a matter of personal
taste. A system that suits your school or district might be
unacceptable in the next county or state. With this in mind.
I'll try to describe Colorgrade accurately enough for you to
judge its usefulness in your classroom while at the same time
indicating my personal reaction to it.
Colorgrade will allow you to keep test scores for up to 40
students in each of six classes. The number of test scores
seems to be limited only by the free disk space, which starts
out at 40 grans. If you have more than six classes, you will
have to put the others on a backup disk. While some
teachers might prefer to have all records on a single disk.
others may even prefer to have a disk for each class
(remember the danger of having all your eggs in one
basket!).
The program is menu-driven and. with a couple of excep-
tions, user-friendly, to the point where the simple three-page
documentation is almost unnecessary. In most cases, des-
tructive procedures are decision-checked, and in most cases
hitting ENTER will allow you to escape from a routine. The
"in most cases" should tip you off to some problems.
The first menu, with set-up routines, uses an odd back-
ward approach — you do number four before number three
and so on. The only reason I can think of for this is to put the
least destructive option at the top. At any rate, option four
kills all files on the disk to clear space for a new year or
semester. You might not want to do this; our school retains
grades until the next school year as evidence in case of
appeals, lost report cards, etc.
Option three sets up class names (subject, period number,
or a combination of words and numbers such as SCI 7 A or
Computing Science 10). Use short, simple names, because
you'll be typing them often and Colorgrade doesn't like
variations in spelling (for example "7" instead of "SCI 7"
crashed the program).
The second choice sets up a grading scale, allowing you to
set the value of an A+oran A-. You'd normally do this only
once at the start of term and then leave it alone. The docu-
mentation does not say if there are default values for this,
and there is no option (that 1 could find) allowing you to see
just what you entered way back in September.
Choice one is for entering student names into each class
file you designated in three. It would be nice to be able to
enter a list of names and then set up class periods. I teach the
same students science and math, for example, and this pro-
gram makes me type in 41 student names twice. Just think
what fun you'll have if you have those students for six or
eight subjects! (And you thought the computer would save
you work!) The names are automatically alphabetized by
what I assume (from the time required to sort my already-
alphabetized class lists) is a basic sort.
Now your gradebook is set up. A second menu appears,
giving you the option of normal operations, print options,
or starting new. Since the print options give you nicely
formatted hard copies of the normal operations, I will not
discuss them in detail. They worked well on a LPVII. looked

good, and would be perfectly suitable lor use as interim
report cards or as a printed backup of your grades (a good
idea, by the way).
"Normal Operations" includes nine options, six for daily
record keeping and three for end-of-term reporting.
1 ) See Grades for Entire Class — This gives you a look at
the current average (raw score/ total, percent, letter grade)
of each student in a class, in pages of about 13 students,
followed automatically by a grade breakdown showing the
number of A's, B's, etc., and the percentage of the class
scoring at that grade level. This option docs not give you the
class average nor does it give you scores on past tests — only
the current average. The grade breakdown gives you an idea
of modality, but Colorgrade does not report mean, median,
or other statistics.
2) See Grades for One Student — Here, you are given a
list of test names with accompanying raw score and percent
for each test. You also get the student's total accumulated
percent and letter grade. 1 felt this was one of the best
features of Colorgrade. It gives a review of student progress;
a printout of this provides a quick report card. I have used
this with my present gradebook program (Tom Mix's
Teacher Database) and it has really motivated students to
make up missed or late work, or to improve their averages.
3) Record Grades — You'll be using this one frequently to
enter the name of a test or activity, the total score possible,
and the score for each student. The names appear in alpha-
betic order on screen, so you might want to sort test papers
before you start entering scores (the random entry in Tom
Mix's version avoids this). Colorgrade will automatically
calculate the percent and letter grade for each student. One
minor annoyance I found was that the disk was accessed

after each two students, slowing data entry. I had to keep
waiting and watching the screen for the next name to come
up. A sound cue, such as those used for incorrect key entries,
would let me know that I could enter the next score. How-
ever, if you don't touch-type, you will not find this delay a
problem.
One major flaw in the entry segment is that there is no
check on the score entered. It is possible to enter a score
larger than the total number of points on the test — and a
score of 290 out of 60 is a guaranteed "A"! A computer check
would save you some work in proofreading for such blatant
typos.
4) Change a Grade — If you do have an error in a score, or
if you need to add scores from late assignments or work
completed after an absence, this lets you fix things up.
5) Delete a Student - This gave me a cheap thrill: every
teacher has a couple of students he'd like to delete. However,
this option only removes a student name from the list. It
apparently clears out all the student's records. Be sure you
get the name right the first time, because there is no decision-
check ("Is this the student you want deleted?") and once
you've pressed ENTER little Billy is gone.
6) Add a Student — As you'd expect, with the added
bonus that the name is automatically placed in alphabetic
order. The new student is given an "incomplete" on tests
currently in file. It is a nice feature.
7) Save Grades - Grading Period — At the end of a term,
or whenever you run out of disk space, you can choose this
option. It saves the current average (letter grade only, as far
as I could see) for each student in a specified class. The lack
of a percent score made this option almost useless to me, as
our reporting is done in percents.

The procedure also kills all your previous records on that
class. This total obliteration is mentioned briefly in the
documentation, but it is not even hinted at on the screen. I
can only hope that Computer Island will put cautions and
decision checks into the destructive options five and seven.
8) List Letter Grades - You can scan the letter grades of
previous terms as well as the current accumulated average
(final) grade. A printout can also be obtained. The ads for
Colorgrade say that the program gives a "weighted aver-
age," but the documentation does not explain how to weight
score;;. Since our school uses a formula for weighting term
scores to produce the course mark, Colorgrade wouldn't
help me in June.
9) Change a Letter Grade — If for any reason a student's
final grade is incorrect, it can be changed.
What would 1 like to see changed on Colorgrade" 1 . Some
format errors break words up on the screen. Occasionally,
some screens flashed past too quickly to read; one such was
the "student not found" message in the Change a Score
procedure. Already mentioned is the need for decision
checks on destructive procedures and the desirability of
checking entered scores against the stated total. It would
have been useful to have some statistics (at least the class
average) computed on each test, and reported. The slowness
of data entry annoyed me, but here I am being picky. My
main problem with the program was its failure to carry the
current percent average over to the final grade and its (seem-
ing) inability to perform its advertised weighting of scores.
There are some things I liked. The grade-scale option
allows you to change the grading scale to suit your school
standards or your needs. The documentation doesn't men-

tion it, but this also allows you to correct for skewed data
and normalize your grades. This is occasionally necessary to
overcome the effects of an examination that is too difficult
or too easy. I liked the automatic current average, given in
the three forms (ratio, percent, and letter grade). The docu-
mentation is adequate, if brief, and assumes you are not
going to want to customize the program. However, the
whole thing is in basic so you can change it if you wish.
Backing up the unprotected disk is a snap. (The documenta-
tion advises you to make one backup and I'd need several to
make full use of the program.) The program is pretty easy to
use once you get the hang of it.
Colorgrade lacks featuers I am used to in the gradebook I
use on the Apple at school and in my present CoCo grade-
book. However, this Computer Island product costs half as
much as my CoCo version and about a quarter as much as
the Apple version. Given this price differential, and the fact
that Colorgrade does its job well enough, it's a good buy if it
will suit your needs. It's a matter of taste.

GTRM— A Good
Text Screen Enhancer
Like many Color Compulcr users who decided to try the
OS-9 operating system, I was amazed at its power and
versatility. At the same time I felt that this remarkable
operating system, running on a 64K CoCo with floppy
drives, was like installing an aircraft engine on a chainsaw.
One of the reasons for feeling this way was the 32 x 16 text
display which is standard on the CoCo. An expanded text
screen program was the necessity that soon became the
mother of invention for GTRM.
GTRM gives your CoCo, running under OS-9. 5 1 charac-
ters on 24 lines of very readable text. Besides the 6K needed
for the high resolution text screen, only seven additional
pages are required for the program. It should be noted here
that under OS-9, one page of memory is 256 bytes, not the
1536-byte graphics page used in BASIC.
It's quite easy to include GTRM in your startup proce-
dure file that is executed when OS-9 is being booted. Simple
and easy instructions are provided for copying the program
files from the disk supplied to the CMDS directory of your
system disk. A demo program lets the program show you
what kind of features it has.
The cursor may be changed from block to underline, and
full movement in all directions is possible making it very
handy for custom text editor programs. Reverse video
blocks with text inside may be created anywhere on the
screen to highlight menus or data displays. A window of
protected area may be defined for text while using the other
portion for graphics display.
Several new graphics commands are included to draw a
line, create a box and start printing text at a specific screen
location. The box command is especially handy for creating
charts with a shading effect that is quite pleasing.
I try to avoid comparisons whenever 1 review programs,
but in this case it seems appropriate. Another program for
OS-9 that has an expanded text screen is O-PAK from FHL
that I have been using for about six months. Both of these
programs carry the same retail price tag of S34.95, yet O-
PAK lets you change or refine the character set. Also, sev-
eral utilities are included with O-PAK for file transfer
between OS-9 and Disk basic. When comparing these two
programs it would be fair to say that O-PAK is more versa-
tile and gives more bang for the buck.
When judged on its own merits, however, GTRM is well
written, easy to use and comes with documentation that is
clear and concise.

Eat Those Dots And Have
Some Fun With Pattipak
Quix Is A Quick,
Strategic, Top-Notch Game
Patiipak is a clone of Pac-Man that's available on tape
or disk. This review was done using the tape version which
CLOADed the first time with no problems. Simple and
complete instructions are provided and anyone who has ever
played Pac-Man will get into it quickly.
The graphics are done in a low, but colorful resolution
mode, and the quality approaches the arcade version. Each
new round of play starts off with a catchy but unfamiliar
tune.
The object of Patiipak is to gobble up as many dots as
possible before being assaulted by the many ghosts chasing
y° u -
There are eight levels of difficulty, and to make it a real
challenge for arcade pros th:re is an invisible maze every
fourth screen. In most Pac games the player is able to hide in
the corners, but in Patiipak the ghosts continue to track you
no matter where you are.
When you manage to clear a screen of all dots, you are
rewarded with a very impressive fireworks display complete
with explosion sound effects. The manual states there is
another fireworks display after the third screen is cleared
and intermission screens after screens two and four are
cleared, but 1 never got past the second screen to see them.
Radio Shack's original joysticks for the CoCo were used
for this review but they are notoriously inadequate for
arcade game control. I did note some sluggishness in
response with them but I'm sure, like many other CoCo
arcade games, best performance can be achieved using self-
centering arcade-type joysticks.

With the release of Quix, Tom Mix has once again taken
an arcade favorite and put it into a version for the Color
Computer. Although it is not exactly like the arcade game
Qix, the play is the same.
You are a small diamond on the edge of a rectangular
playing screen and your goal is to box in at least 75 percent
of the screen by outlining boxes with your man. To make it a
little harder, you can only move along the edge of a box.
There is also a red line moving around the screen, this is the
Quix. If it touches the outline of an unfinished box, you lose
a man. There are also other enemies, and things to make it
harder to stay alive; at higher levels, there are even two
Quixes!
Quix is different from most of the other games 1 have
seen. It has the combination of a fast, arcade pace, and the
strategy of chess. You must watch where the Quix is (as well
as all of the other nasties) while drawing a box. lest you lose
a man. There is a fine line between a game being too easy and
too hard. Quix rides right in the center of this line, being easy
enough to get quick results, but hard enough to be challeng-
ing when you become an expert.
The directions are bnel and concise, but all ol the neces-
sary information is there. 1 have never played the arcade
predecessor of Quix, but 1 was able to start playing almost
immediately. Nothing is left to the imagination in the direc-
tions. You arc told how to get new men, how to load the tape
or the disk, as well as what to expect on each level.
1 would suggest this game to anyone who is willing to try
something a little different. It is well done as are the other
Tom Mix programs 1 have seen. Quix is a top-notch game.

Develop Programming Skills
With TRS-80 Color Computer
And MC-10 Programs
Radio Shack has always taken a lot of heat for their Color
Computer instruction manuals. I think for the most part
these manuals are well-written and the criticism comes from
not being able to please everyone. There is one area in the
manuals 1 feel is kind of weak; that is, the lack of practical
programming applications and useful examples. A novice
does not have to work with the manuals long before he is
looking for some useful programs to work with while he
develops his programming skills. If you are one of many
faced with this situation, one avenue to consider is to pick up
one of the growing selections of Color Computer program-
ming books. That brings us to the topic of this review, which
is a new book containing basic programs found on Radio
Shack's shelves. TRS-80 Color Computer And MC-10 Pro-
grams is written by William Barden. Jr., the premier Color
Computer teacher, programmer and writer.
The coverage of the Color Computer and the MC-10
(Microcolor Computer) in one book is a natural combina-
tion because Color BASIC and Microcolor BASIC have very
similar dialects. There are very few dissimilarities and they

are highlighted whenever encountered in any of the pro-
grams presented in this book. Note that the book concen-
trates on Color basic and does not use any of the powerful
commands to be found in Extended Color BASIC. I'm sure
that this was a conscious trade off made by the author
wanting to aim his book at the novice-to-intermediate pro-
grammer. The book does take almost full advantage of one
of the most feature-rich BASICS available in this market.
The book has 184 pages packed with a variety of pro-
grams of all types — educational, games, math, practical,
music, business and others; 40 programs in all. Some alone
may be worth the price of the book. As examples, there are:
a detailed amortization schedule program with output to
either the screen or printer, a perpetual calendar program, a
mailing label program, an ohms law calculator, a BASIC
word processor and many, many more. If you are consider-
ing this book, pick it up and leaf through the table of
contents; there should be something for almost everyone.
The programs in this book are mostly designed for a 4K
system. In fact, all but three will run in 4K of memory. The
compactness of the programs do not distract from their
usefulness.
This book, which is a compendium of useful programs,
can be helpful to those learning programming but can be
used by anyone interested in obtaining inexpensive software
for their computer. The style used in the book concentrates
on presenting the programs with a brief tutorial on how they
work. Each program includes a background section describ-
ing the particular algorithm or basis for the program as well
as a section of special notes detailing the hardware require-
ments. Differences between the Color Computer version
and the MC-10 version are clearly described and sample
printouts and screen displays are often included. This tech-
nique used to present the programs is very effective. 1 should
also point out that this book uses actual reproductions of the
program listings rather than typeset listings. This results in a
much more accurate listingand obviously much less frustra-
tion.
My only complaint about the book is minor. The Color
Computerand MC-10 have the capability of storingdata on
tape but this is only used in one program, the word proces-
sor. All other programs using data rely on embedded data
statements. This method is much simpler but does not allow
full advantage of the computer system of which cassette
storage is a working part. With embedded data you are
limited to the memory capacity of the computer. With tape
data storage you are theoretically limited to the length of
tape available for storage (megabytes). I believe that some of
the programs could have benefited from tape storage.
Overall, my impressions of this book are good. There is an
excellent variety of useful programs presented in an easy to
read and understand style. The author is one of the most
renowned programmers and authors in his field; you
couldn't find a much better source. I recommend TRS-80
Color Computer And MC-10 Programs to any novice to
Color Computing or anyone looking to beef up his Color
library. The price is definitely right and the book is as near as
the nearest Radio Shack store.

Assembler Language
Programming Toolkit —
A Powerful Debugger
By Sluart Hawkinson
The Freeware concept seems to be catching on all over the
country. 1 recently attended a software festival in Portland.
Ore., where noted Apple author Paul Lutus donated a
diskette of software to festival goers. Now the CoCo Free-
ware Clearinghouse has come out with a new freeware offer-
ing. The Assembler Language Programming Toolkit
(A LPT) includes an Editor/ Assembler for machine lan-
guage programming and a Monitor, Disassembler for
debugging machine language programs.
The A LPT provides a suitable set of tools for learning
machine language ( M L) programming. In conjunction with
a book such as Bill Barden's TRS-80 Color Computer
Assembly Language Programming from Radio Shack, you
have a good beginning. The A LPT package is not compat-
ible with Radio Shack's EDTASM+. nor is it as complete.
But that may not be important while you are learning to
write M L programs. Your first efforts will be short practice
pieces. After you gain more experience, you will want to
graduate to a more powerful, faster package.
The Editor/ Assembler part of the package enables you to
write assembler mnemonics using a full screen editor and
then assemble the program into machine language instruc-
tions (hexadecimal bytes). The editor is specifically geared
to assembly language programming. It features defined
fields for labels and assembler op-codes (ML instructions).
The assembler uses the source code produced by the editor
and transforms these instructions into machine language
object code.
The Monitor/ Disassembler reads the object code file and
allows you to debug the program in a very controlled envi-
ronment. You can step through the program execution,
instruction by instruction. The monitor shows you the con-
tents of the microprocessor's registers at each step. You can
change registers and memory at will, as well as jump to new
sections of code. The disassembler feature allows you to
examine the machine language code by showing the corres-
ponding assembler mnemonics.
After your program is debugged, the monitor can save a
copy of the machine code in the standard Radio Shack
format as a binary file. This version of the machine language
program can then be loaded and executed normally using
the LOADM (disk) or CLOA DM (tape) command followed
by the EXEC command.
The BASIC programs are supplied on either tape or disk.
Send the CoCo Freeware Clearinghouse a blank disk or tape
and a self-addressed mailer with return postage. After you
have tried it out, you may send a contribution. The instruc-
tions for the package are supplied as a program which prints
a seven-page document. You simply run the first program
FREE301A to obtain the listing.
The rest of the package is provided in two program seg-
ments, FREE301B (Editor- Assembler) and FREE301C
(Monitor/ Disassembler). A fourth program. FREE301D
on the disk version, can be used as a convenient menu-driven

program loader. I renamed this program "MENU" to make
operation simpler.
The lull screen editor has commands to insert, delete, and
renumber (duplicate lines). You copy to new lines by over-
typing an existing line number. This creates a copy of the
current line with the new line number. You move a line by
first copying to a new line number, then deleting the old line.
The arrow keys provide lull screen cursor control. Var-
ious shift combinations move the cursor to the start of a
page or exit the editor. The CLEAR key moves the cursor to
the next op-code field. The editor has very slow keyboard
response, so you must type at a slow, measured pace. You
are limited to the screen width for program lines, and com-
ments must be placed on separate lines.
After entering your program, you may save the source as
an ASCII file to either tape or disk. The editor uses the
default extension "SRC" to indicate a source file.
The assembler takes the source code from memory and
performs a two-pass assembly. This operation, in BASIC, is
much slower than if the assembler were written in machine
language. The assembler also has some syntax restrictions.
Not all the standard mnemonics are supported. For exam-
ple. PC relative addresses are referred to as *P' rather than
•PCR', while the direct page register is referred to as "Q'
rather than "DPR*. No index arithmetic or label offsets are
supported.
Since the editor uses the shifted arrow keys to move the
cursor, the assembler must refer to indirect addresses with
parentheses rather than square brackets (SHIM -right arrow
and SHU- l-down arrow). These differences force you to be
very careful when entering programs from published listings.
You must also be aware of the limitations of the
assembler's output and error messages. You cannot get a
directly executable file from the assembler. The object code
file (default extension "OBJ") must be read into memory by
the monitor program. Also, the assembler doesn't produce a
symbol table, which is useful for debugging. The error mes-
sages are limited to four cryptic statements.
The slow assembly is monitored by a moving bar at the
bottom of the screen. This performance monitor tells you
how far the assembly has progressed, showing you that the
program is still working, and hasn't "gone away" due to a
programming error.
The Monitor; Disassembler loads assembled programs
and allows running the program in a very controlled
manner. It also displays the program by disassembling the
machine codes to assembler mnemonics. This makes debug-
ging and tracing program flow much easier.
The monitor displays registers and memory, and allows
both to be easily changed. The display for the condition
register. CC. would be more useful if each bit were dis-
played. The CC register has five condition bits (negative,
carry, etc.) interspersed with three interrupt control bits.
Separating them would make debugging much simpler.
One monitor command displays a HELP screen with
short descriptions of all the commands. Normal address and
memory input is given in decimal. The documentation fails
to mention that you can specify hexadecimal input by using
the "&H" prefix. The displays from the monitor are a mix-
ture of Hex and decimal values. It would be much better to
uniformly provide hexadecimal input and output. The
beginner would learn to use this important mode much
faster.
The programs you load and debug using A LPT must be
located at address 30000 (7530 Hex) and above. This limit
stems from the monitor program using the lower 30K of the
32K system. If your program uses graphics pages, you must
limit the program to four pages (one Hi-Res screen) due to
memory constraints.
Besides the restrictions on memory mentioned above, the
editor restricts the size of program that can be assembled.
The assembler also has some address or mnemonic restric-
tions. The slow editor keyboard response seriously limits
typing speed for experienced computerists.
I lound several syntax errors in the monitor program,
these appear to arise mainly from eliminating blanks in the
program. Six corrections are needed:
Line 190: add space in phrase \SB=MI ELSE'
Line 200: add space in AR=M I ELSE'
Line 380: add space in "PW=PP TO'
Line 820: add space to 'K = M I TO'
Line 900: add space to'POKEMI.N ELSE'
Line 1820: add •<!' after J in 'IF.KI OR K<l'
1 was also puzzled by the 'SA\ set argument command.
Nothing describes it in the documentation.
The A LPT package provides a good set of BASIC pro-
grams for introducing assembly language. You may soon
graduate to a full featured ED TASM if you write assembler
programs of any length.
The Freeware concept has produced another good pro-
gram for the Color Computer enthusiast. I hope there will be
many more to follow.

File Handling Capacities
For Fast, Flexible,
Sophisticated
Database Management,
There's Elite*File
By Ed Lowe
To support my computing habit 1 spend most of my day
managing the operations division of a company which spe-
cializes in training people in both the public and private
sectors on how to best use microcomputer personal produc-
tivity software on IBM PCs and similar computers.
On the most-wanted list is a system called dBA SE II (and
its follow-on dBASE I If), perhaps the most widely used
database management system (DBMS) for the microcom-
puter. It is also one of the hardest to master without constant
practice and use. At least half a dozen books have made it to
the top by explaining this system in terms that the lay user
can easily grasp. It takes quite a while to make use of its
powerful features.
A database is a collection of data on disk, organized to
provide easy access by people and computer programs. A
DBMS, then, is a set of programs controlling access to the
database.
According to a recent issue of PC Magazine. "Databases
generally fall into three categories: hierarchical, network,
and relational. The first two are usually found on mainframe
computers and minicomputers and are designed to handle
very large applications.
"Relational databases ... are less complex in design and
are easier for most people to grasp conceptually."
The simplest DBMS is a file management system that
stores data in individual files made up of records and fields
and containing a description of each field and one or more
indexes to keep the file in order by key fields. The file
management structure is ideally suited for terminal entry
and has certain other unique characteristics. BASIC data files
don't fall into this category.
Elite*File, a relational DBMS, is the third of Elite Soft-
ware's trilogy of applications packages for the Color Com-
puter. It needs a minimum of 32K with one drive and is
completely interactive with the other two: Elite* Word, the
word processor, and Eliie*Calc. their spreadsheet offering.
In my opinion, it offers power and features comparable to
dBASE II in many respects, even though on a smaller scale.
When we consider the cost of a 64K. CoCo and a DBMS
such as Elite*File (now S259.95 and S74.50 respectively)
compared to that of an IBM PC and dBASE II (roughly
$3,000 plus $400). we have an unsurpassed bargain for both
personal and small business database management of
almost any kind.
1 was very impressed by Elite* File's file handling capacity.
1 think most of us would be hard-pressed to exceed its
handling limits under most circumstances. Consider the
following:

(♦Theoretical. Actual size is calculated by dividing max
available disk space by number of characters in file's
definition.
**String values are automatically converted to numerical
data when needed, although the user must be aware of
specific needs.)
These comparisons with dBASE II a.rt simply to establish
a point of departure. We aren't likely to see dBASE II on a
non-CP/ M CoCo in our lifetime, I'm sure! But not to worry,
as long as we keep getting the likes of Elite* File. The latter
doesn't have a lot of bells and whistles, but it'll get the job
done well both at home and in the shop. So let's now
concentrate on Elite* File itself.
(When I use "easy" in this review, it is because Elite* File\s
easy to use — although, as the manual says, you can't "fake"
it; and it's the easiest one with such power I've come across
yet.)
I won't itemize its features because they are well enumer-
ated in Elite Software's ad in the pages of this magazine.
Still, 1 cannot see a single advertised claim that I would label
as mere hype. I've had a chance to exercise the majority of
the features more than once and can report that, except for a
few instances when I had to go back and dig around in the
manual to check a procedure, 1 encountered little difficulty.
That is not to say that their manual wins all blue ribbons for
clarity and style. The system itself saves the documentation.
But more about that later.
A Standardized Data Format
Data format is interactive with both Elite* Word and
Elite*Calc in that text and data can be passed among the
three. Would that they could all reside in memory at the
same time and pass parameters back and forth! I did not
have Elite*Calc to interact with, but Elite* Word proved
easy to use with Elite* File and vice versa. Its data files may
easily be read using Disk Basic's direct access I/O structure
and the steps outlined in the manual. (See Listing I for a
routine I used to prove it to myself.^
No Disk Swapping
Elite* File is written entirely in machine language, except
for a small loader which sets up the CoCo for work. All of
the system resides in memory, so single drive users can insert
a data disk after booting the system and forget about any
disk swaps. I must admit, though, that I seldom remembered
December 1984 THE RAINBOW 241
to remove the system disk and insert the data disk before
starting to work!
Menu driven, it offers lots of handholding and error
trapping features to prevent your bombing out. In fact, it is
very hard, as far as 1 can tell, to bust the program. I did
discover a minor irritant: my right pinkie has a tendency to
want to come down between the hyphen and BRF.AK keys.
On a couple of occasions the BREAK key won the tag. auto-
matically aborted record entry, and I was summarily
returned to the main menu. No harm was done, however,
since files are closed upon return to the main menu. It just
made me gun-shy.
Error messages (in CoCo's now infamous mnemonic for-
mat) are displayed momentarily, and in most instances you
arc returned to a selection menu to correct your option or
data input with no program interruption. All menu selec-
tions and prompts are clear and to the point. Selections are
all made with single keystrokes.
The Same Old Characters
Perhaps I'm getting spoiled, but I did not anticipate Elite*
File 's use of CoCo's built-in character set and its 32 x 16 text
display. I had expected it to have its own character generator
to put more information on the screen at a time. Perhaps
we'll see future versions so equipped. Many serious users
have upgraded to monitors capable of displaying much
more than 32 x 16. Perhaps speed and RAM were the
author's primary concerns.
Defining The File Structure
The most important step in setting up a database file is
carefully planning the actual file structure. This normally
involves determining the fields needed and naming them, the
type of information to be entered into each field, and the
width or maximum number of characters each field should
hold to effectively handle all of your data. After you have
entered data into it, you cannot easily change or modify that
structure without losing all of your data. Plan carefully
before executing.
Even so. defining a file's structure should be simple (easy?)
with Elite* File — perhaps even deceptively so. Simply give
each field a name and separate that from the width by a
colon and you're off and running. Only character fields arc
accepted, so you don't have to fret about numerical or
logical fields. Its simplicity cannot be overstated, believe me,
but you must plan ahead to avoid wasting time trying to get
it right. Elite* File will keep track of the complete file struc-
ture from that point on. Before actually entering data into
the first record, you may modify the structure as often as you
want until you gel it just like you want it. If you later decide
the structure still doesn't fit your needs, you can copy it to a
new file, add, modify or delete fields, and then transfer or
"refile" the data into the new file.

One of the databases I created is for a product search
designed to provide information on hardware and software
products available for the CoCo. It mirrors one 1 maintain
for the IBM PC and PCjr on dBASE 11. Figure 2 lists its
structure which, had 1 not been investigating, should have
taken no more than 30 minutes at best, start to finish.
Format Reports
After you've defined a file's structure, you must format
reports to route selected data to the screen or printer. Such a
report may be generated in either the "command mode" for
simple needs or through structured programs for more fixed
needs. Using Elite* File's programming language should be
easy. It follows today's trend toward plain English com-
mand words. You'll find yourself experimenting somewhat
to get the desired outcome, because the manual skimped a
bit in providing enough in-depth examples to enhance the
learning and using process here. The system has enough
flexibility to deliver almost any kind of report you'll need at
any printed width you specify.
There are provisions for including a header title in a
formated report. Its limit is 50 characters, a limit not men-
tioned in the manual.
Another very important feature which could benefit from
more clarity is the CALCulation function. When trying to
calculate the three formulas in Figure 3, I consistently got a
Syntax Error ("SN IN CALC") until it dawned on me that
only one calculation may be placed on a line unless separ-
ated by colons. This function, too. is not sufficiently
explained in the manual.
Figures 2 and 3 show a programmed report format file
written using Elite* Word, and a resulting sample printout.
The Documentation
As with all software review assignments, 1 found myself
paying particular attention to the accompanying documen-
tation to determine if it clearly and adequately supports and
explains the various features of the system.
Elite* File's documentation gets an adequate rating. On a
scale of one to five, that translates to three stars. Basically,
they seem to have tried to compress it too much and as a
result do not give examples and expansions of features with
enough depth in several cases. The user finds himself exper-
imenting, for example with the reports formatting parame-
ters to get a firm handle on them. If you're really serious,
though, that can be an excellent learning technique.
The manual is divided up into three user parts: general,
advanced, and expert. The intent is good. The general user
section will get you started with a database today. Learn
more and embellish on what you've got. I like that idea. I
found myself reading the whole thing several times before
starling the programming phase.
A newcomer to the CoCo can make use of Elite* File and
get very usable results. An experienced user with a good
grasp of programming can really make it sing. In trying to
wring it out. I found myselftryingall sorts of things and then
checking the manual to see what it said. (Without an index,
that can be slow!) Most of the time it's there.
I like Elite* File and would readily recommend it to
anyone needing a good. fast, flexible, basically uncompli-
cated yet sophisticated DBMS. Its power and speed have to
be seen to be appreciated.

Hockey Fans Will Love
Ice Hockey
Quick now, what is it that brings out the fanatical quali-
ties of Canadians and people who live in the major cities of
the eastern United States?
If you guessed the Color Computer, you're not wrong.
But the answer we were looking for was ice hockey, because
this happens to be a review of a new game recently released
by Computerwarc called Ice Hockey.
Hockey fans of both countries will love this version. It is
of arcade quality, complete with hockey stick-equipped
players, a lively puck, nine levels of challenge and lots of
realistic offense and defense.
A dramatic opening gives you the option of playing the
national anthem of the United States or Canada, with the
flag of the designated country displayed while the music is
played.
You have a choice of one or two players. If one is selected,
you play against the computer, which in this case, is a very
capable opponent. You have two players on your team, each
of whom is expected to be equally as good on offense and
defense. Their success, of course, depends upon your prow-
ess with the joystick.
The game is divided into two 10-minutc halves, with a
short musical intermission between play.
The scores are displayed at the top of the screen, with the
team possessing the puck constantly updated as the game
progresses.
Graphics, sound and challenge are all superior in this
tremendous demonstration of how a fast-paced sports game
can be handled and still retain the suspenseful and skillful
elements that make it a traditional favorite. As in any
arcade-type game, it takes awhile to master the joysticks, so
expect some high-scoring games for awhile. When you get
the defense down pat, the scores become more realistic.
The only problem I have with the program is that there
doesn't appear to be any way to make a backup copy.
If you like hockey or sports games, good arcade games
that demonstrate CoCo's full potential, or are just a parent
who wants to keep junior busy. Ice Hockey belongs in your
library.

Finding A Wealth
Of CoCo Knowledge
In Rainbow Hints
By Joseph Kolar
Rainbow Contributing Editor
Hints and suggestions are strange
coin of the realm. They have
different value to different peo-
ple. Some hints are worth a small for-
tune in computer time to some individ-
uals. Some hints are gimmicky and
worth nickels and dimes. Some hints are
quite valueless. But. the person who
fails to stoop down to inspect the hints
and walks on by might just as well kick
THE rainbow aside.
THE RAINBOW is chock full of useful
information worth scooping up and
being stored in the vaults of your bank
of computer knowledge. There are piles
of "coins" waiting for you. It is up to
you to gather in the loot.
This article is more blatant about it.
You will find a flea market offering of
variouscoins. Some hints will be useful.
Pocket them! Some will surely be use-
less. Pick them up and pass them to the
needy newcomer, who hasn't discovered
the pot of gold called THE RAINBOW.
Browse through the hints at your leisure
and say to yourself, "Now, why didn't 1
(Joseph Kolar is a free-lance writer and
programmer dedicated to proselytizing
for computers in general, and the CoCo
specifically.)
think of that? Let me try it out and see if
it works for me."
Looking into my secret vault for the
"gold coin" that has reaped dividends
for me, 1 can find none that outmatch
the one 1 will grudgingly offer you.
Newcomers are blessed with varied
typing techniques and abilities. Each
newcomer brings his special style with
him. Most beginners are neither expert
typists nor unable to type text with at
least one or two fingers. The first order
of business for the newcomer is to copy
listings.
The big problem confronting people
new to computing is the confusion of
the new computer vocabulary that
makes up a listing. Their big woe is
being unable to keep their place in a
listing. They are forever losing their
place and dropping to the next line or
skipping part of a line.
Asmajoran irritation as that maybe.
we all make peace with ourselves and
devise some method that suits us well to
cope with this annoyance. Soon enough,
we are typing the listings but at a price.
We are makingall kinds of errors. Copy-
ing a listing is very demanding and must
be done exactly as listed.
Many experts advocate looking at the
listing and not sneaking peeks at the
screen. Wrong! It is better to watch the
characters as they appear on the screen
and sneak peeks at the listing.
The experts will scoff at this bit of
wisdom. They wouldn't be experts if
they didn't scoff. But. as newcomers,
follow this line of reasoning:
Copying a listing is very demanding
work. A comma instead of a period may
give you an error message. A zero
instead of an O or a one instead of an 1
will do the same. Other errors will be
more insidious and cause much text-
listing comparing. Now, if you watch
the screen as you copy, you can watch
the characters that appear on the screen.
Many errors are due to incorrect finger-
ing and can be corrected immediately.
Taking a quick peek at the listing will
verify if what you typed is what the list-
ing called for. The key word is imme-
diately. You correct your typing mis-
takes as you are keying in the listing.
I have found by watching the charac-
ters appear on the screen that it is fun
and very satisfying to correct any error
before it goes too far. After changing
over to the fascinating 'see what you are
typing' routine, about 85 percent of my
errors are remedied before 1 even try
that first tentative run of the completed
listing.
Quite often, depending on the pro-
gram, you can pause and RUN what
December 1984 THE RAINBOW 245
you have copied so far. If you get error
messages (such as SN), LIST the pro-
gram line, and correct the error. RUN
again and if you get 'OK', the computer
is satisfied with what you keyed in. That
is not to say that all errors are elimi-
nated. You can also clear up a lot of TM
or FC Errors in this manner.
Sometimes, on these trial test runs,
you may get U L because a program line,
usually containinga GOTOov GOSUB,
references a higher line number you
hadn't reached yet. As a newcomer, you
can't win them all. There are ways to get
around this but not in the scope of this
article. You could RUNx where x is the
next line number.
This is merely a "starter" to set you on
the road. The only way to develop your
own system is the old fashioned way,
hard work and much practice.
The second most useful hint is old-hat
to most programmers. Make frequent
copies of work in progress. After keying
in some lines, make a copy and take a
breather. This insures that all the trou-
ble you have gone through to trap errors
is not in vain. It doesn't make sense to
search for mistakes only to lose the
program.
The third most useful hint is to save
all your working tapes. File them away;
The only time you will want to refer to
them is five minutes after you erase
them.
Mr. Allen W. Stuart. Jacksonville
Beach, Fla., offers the following hint:
If you are having trouble locating the
blank space in front of the beginning of
a listing on your tape, (to avoid sitting
on top of the listing and getting the I/O
Error) simply run the tape near the end
of the preceding program. Type A UDIO
ON ENTER MOTOR ON ENTER and
any letter (don't ENTER). You will hear
the precise end of the preceding pro-
gram. Now, ENTER and you will get an
error message, but you will be right on
target for the desired location.
Mr. W.P. Frame, Hershey, Neb., had
a problem with his CTR-80A. The PLAY
key was slipping. I quote,"! took off the
back and took a piece of fine sandpaper,
cut about Vt" wide and threaded it up
between the button and the bail, held
down the button and pulled out the
sandpaper. After about five passes, 1
had restored the hook in the button that
held it to the bail. It worked!"
Mr. Ahsan A. Akmal, Chicora, Pa.,
offers a simple, inexpensive hint; easy to
implement that does not harm ordisfig-
ure the CoCo. He had a problem in
keeping his fingers on the home keys of
his new CoCo 2 typewriter keyboard.
He used a label-maker, punched out
two dots (he used the period), and used
a paper punch to make neat, round
dots. He affixed one dot on the 'F' key
and the other on the 'J' key. Upon
further experimentation, he put a pip on
the '2' key to locate the quote mark, on
the '4' key for that ubiquitous $; on the
minus key to locate the minus and equal
sign; on the left arrow to avoid hitting
the CLEAR key when reaching for the
back space.
Mr. Chuck Ziehl, Lockport, N.Y.,
reports that he was using a 'D' board
CoCo that would go to garbage after a
half to one hour. He investigated and
traced the problem to the SAM chip
and heat sinked it to the RF shield. He
successfully took a 3 /s" thick by Vi" wide
by 2" long piece of aluminum and using
lots of heat transfer paste, placed it on
the SAM chip and screwed the heat sink
to the RF shield with one screw.
On another note, Mr. Norman Wong,
Nanaimo, British Columbia, offers, "In-
stead of 140 IF IN KEYS ="" THEN
140, which waits until the user presses a
key, one can use 140 EXEC&HA171.

The advantage of the latter is that it uses
up less memory; it does not terminate
the program if the user presses the
BREAK keyand itdisplaysacursorwhile
it is waiting thus indicating that the
computer is not hung up."
Women have a penchant for copying
recipes on file cards and storing them
away in a plastic file-card holder. Mrs.
Betty White, Kirkland, Wash., reports
that she copies vital information about
basic statements and functions onto 3"
x 5" file cards, adding notes that may be
useful. When she is working on a pro-
gram, she yanks the appropriate recipe
for easy completion. Naturally, the card
file is easily stored.
Another innovation she reports is
that she ripped out the PRINT® work-
sheet from the "Getting Ahead With
Extended Color basic" manual; glued
it onto a heavy cardboard backing and
covered it with a transparency from an
overhead projector. A grease pencil is
used to design and locate graphics when
using PR1NT@ locations on the trans-
parency. Erasures are made with tissue.
If any reader has some hint they find
useful, you may want to share your
innovation with other struggling new-
comers. Keep in mind the fact that the
hint must be readily understood by a
newcomer. If you have a hint for ad-
vanced users, send it to the rainbow's
"Letters to the Editor" column.

Introducing

By R. Bartly Betts
Rainbow Contributing Editor
with Programs by Chris Bone
As an introduction to this month's
column, 1 would like to draw
your attention to an innovation.
You will be finding notes 1 call "Byte
Master Bits," which are short explana-
tions of new concepts. 1 think they wil 1
make communications easier.
First, I would like to say thanks to the
many who have taken the trouble to call
or write Chris and me. Knowing the
popularity of THE RAINBOW, I knew
there were lots of readers out there, but
it is great to get a chance to meet some of
you, if only by letter or phone.
Second, regarding letters, there have
been some major changes in my life and
one of them is my address. If you want
to contact either Chris or me, please
write to:

The Stars At Night
Yes, my love of the Color Computer
finally drove me to the ends of the earth.
1 left the beautiful 65 to 75 degree
weather of southern Canada to come to
Texas, where every day is determined to
outdo the previous day's 100-plus de-
gree weather. Luckily Radio Shack took
pity on my CoCo plight and gave me a
job as a technical writer — and 1 love it.
1 guess Radio Shack also feels I might
work better as part of a team. Even as 1
write this, co-author Chris Bone is also
wending his way to the Texas plains. He
is joining Radio Shack as a technical
researcher (that means he looks for
technical errors in the Tandy manuals).
We will be working in the same depart-
ment while he pursues his scholastic
studies. You can contact Chris by writ-
ing to my address until he has a perma-
nent one.
Getting Things Straight
Speaking of teams, it seems that I
didn't do well on my own. Chris has
found some errors in the last column:
these occurred while he wasn't here to
correct me. As well, there are a couple of
places where I failed to get the correct
version of a listing into the program.
Aside from the regular material, 1 hope
to clear up some of these problems this
month.
To begin, I mixed up some of the
information on indexes and accumula-
tors. My explanations were right but
some of the examples 1 gave were wrong.
Following are the examples the way
they should be. We have also added
other examples to help clarify how you
can use registers to manipulate data.
The following examples deal with the
use of the comma, pound sign, dollar
sign, plus sign and minus sign in assem-
bly language source listings.
The first three items of each line give a
sample assembly language listing. The
remainder of the line is an explanation
of what the listing does.
0010 LDA ,X Loads A reg-
ister with the value in memory location
pointed to by register B.
0020 LDA ,X+ Same as
above but adds one to X upon comple-
tion of the operation.
0030 LDA .-X Subtracts
one from register X then loads the A

azine editor and store owner now resid-
ing in Fort Worth, Texas. He has owned
and operated a Color Computer for
over three years and is presently taking
an electronics and computer course by
correspondence. Chris Bone is a college
computer science major and has been
programming for more than three years.
He averages between six and nine hours
a day on the CoCo.)

ory location Hex 10.

0050 but loads from memory location

There were a few other problems but
they didn't take quite as much explana-
tion and so they are included at the end
of the program.
Introducing Screen 51
Now to get on with this month's
work. This is the month we will provide
the first installment of the 5 1 -column
text generator mentioned in previous
issues. In order to give you the best
chance of understanding how it works, 1
am presenting it in installments. This
allows more details on how it operates. I
know that can be frustrating for those
who arc only interested in the program
and not how it operates but, after all,
the purpose of this column is to teach
you to write your own programs. Pre-
senting a bit at a time, so you can see
how the sections work, will help you do
this.
"The Most Significant
Byte is the first byte in a
hexadecimal number.
The Least Significant
Byte is the second byte in
a Hex number."
First Some Homework
Before delving into the program,
however, let's see if we can clear up a few
more mysteries. Below is a chart show-
ing all of your computer's registers with
a brief description of them. You might
want to keep it as a reference.

problem is that there is really nothing to
explain. As you already know, a byte is

a hexadecimal number. The Least Sig-
nificant Byte is the second byte in a Hex
number. In the number 3F4C. 3F is the
Most Significant Byte and 4C is the
Least Significant Byte.
You probably will be pleased to dis-
cover that the previous chart illustrated
most of what you will need to know
about the 6809 registers. The registers
seemed complicated to me at first, but
when 1 finally listed them all together, a
lot of the mystery cleared up.
A and B are the registers used the
most. When a 16-bit operation is re-
quired, they can be combined and are
called register D. You will soon be
learning about indexed addressing with
registers X and Y: it isn't complicated.
Register U serves a dual purpose and
can be used like registers X and Y as well
as used to keep track of a stack you set
up in memory. Register S operates the
same as register U except that it is also
used by your computer's CPU to store
addresses for returns from subroutines.
Byte Master Bit 2
A stack is a data structure or storage
location that follows the rule of "first in
last out." In other words, when you put
data onto a stack, it piles up like a stack
of blocks. When you pull data from the
stack, the last data (block) you put on
the slack is the first to be pulled.
The following diagram demonstrates
how a stack works. It assumes that the
U register has been loaded with the
value of S3F00.
Operation
Stack
Value
li Points At
I.DA 43
PI St A
43
3EFF
I.DA 12
PI St A
12
3EFE
I.DA 10
PUSt! A
10
3EFD
Following these operations, U now
points to the last entry on the stack,
which is 10 and which is located in
memory address S3EFD. If you now
issued a PULU A command, the value
to be pulled into register A would be 10.
I will be writing more about stacks in
the future and you will get a much
clearer picture when you sec them in
use.
The Direct Page register allows you
to organize your computer into 256-
byte blocks of memory called pages.
You can then treat these pages as com-
plete memory units. You will see from
future examples just how handy this
register can be. The DP register can be
set to represent the Most Significant
Byte of the address.
The Condition Code register is not
really a register at all but a grouping of
eight one-bit flags that are used to
reflect the results of an arithmetic oper-
ation. To be technical, the CC register
has five status flags, two interrupt con-
trol bits and one bit to tell the processor
what to do with the registers when an
interrupt occurs. If this means nothing
at all to you. don't fret, such things will
become clear as we continue.
How The Stack Stacks
The best way to clear the air is to give
some examples. After you have loaded
and executed your editor/ assembler,
type in the following program to further
illustrate how data is pushed and pulled
from a stack.

Here is how it works:
Line 0010 sets the program origin at
3F80.
Line 0020 sets START as the label for
the beginning of the program and loads
register A with Hex 12 or decimal 18.
Line 0030 loads register B with Hex 43
or decimal 67.
Line 0040 loads register U with Hex
3F00. Because the register used is L), this
command initializes a stack area at
memory location 3F00.
As you know, register D is registers A
and B combined. The Least Significant
Byte, register B. is pushed on the stack
first. The Most Significant Byte, regis-
ter A. is pushed on last. Thus the value
from register A is accessible first.
Register U always points to the last
used memory location; it now points to
value 3EFE.
Line 0090 uses the PULU B command
to get the last value on the stack, S12
into register B. Register U now points to
memory location 3EFF.
Line 00 100 pulls the next value $43 from
the stack into register A and, as U fol-
lows the stack, it now points to S3F00
again.
Although it is not the most efficient
way to do it, the above routine accom-
plished a swap of the values in registers
A and B, using registers A, B, D and U.
But What Is The Condition?
Although Condition Codes are a bit
more confusing, they are going to be
simpler to explain, mainly because I am
going to do very little explaining. There
is not a great deal you need to know
about the CC register at this stage
because, until we get into more complex
programming, your assembler will han-
dle keeping track of the flags for you.
The following listing illustrates this.

Byte Master Bits 3
You will notice in the previous listing
that instead of using the ASCII value of
an alphabetic character, Chris uses the
character itself, preceded by an apos-
trophe. This is perfectly legal and is a
great shortcut.
Actually you can only see the opera-
tion of the Condition Code register in a
roundabout way in this illustration.
Here is how the program works:
Lines 00 1 and 0020 load the A and B
registers with SI2 and $43. These num-
bers have no special significance.
Line 30 pushes the B register on the S
register stack.
Line 40 compares the value in register A
with the value now on the stack, then
increments the S stack pointer by I.
If the values are equal, Line 50
branches to Line 80 (label EQUAL) and
register A is loaded with the ASCII
value of E (for equal).
If the values are not equal (which is
the case here) the program falls through
to Line 60, loads register A with the
ASCII value for N, for not equal, and
stops.
As it is, the program does nothing
visible but it could easily be expanded to
accept input from the keyboard and
compare the input with another value,
then print whether the values are equal
or not equal on the screen.
What does this have to do with the
Condition Code register, you might ask.
Well, the CMP (Compare) command
actually subtracts the two values being
compared but, rather than storing the
result anywhere, it sets certain flags in
the Condition Code register. These flags
indicate whether the result of the com-
parison was equal or not equal. What
does this mean to you? Mostly it means
that you can forget about Condition
Codes at this stage of your schooling.
All you really need to know for now is
that CMP can be used to compare two
values.
Back To Basics And On To Screen 51
The next two listings are: 1) a huge
data table in source code that contains
the data to create the characters to be
used by the program and; 2) a BASIC
program to show you a little of how
your 5 1-column screen program is going
to work. You won't be able to do much
with the listings this month but in the
next column we will tie things together a
bit more.
For now, enter the source code with
your editor/ assembler and save it to
disk or tape. Also assemble the code to
disk or tape and give it the name
SCREEN5I/BIN. If you don't know
how to do this, check back issues of the
"Byte Master" column.
Next, type in the following BASIC
program, make sure it is correct and
save it to disk or tape. Before you run
the BASIC program, load SCREEN5I/-
BIN into memory using the LOA DM or
CLOADM command. When you run
the BASIC program it will put you into
the graphics screen mode. Now when
you type on the keyboard, you will see a
new character set. with both upper- and
lowercase letters.
Don't worry that typing is slow and
awkward. This is because of the BASIC
driver. When you have the rest of the
program, it will handle any typing
speed. All this program is suppose to do
is give you a taste of what is to come.
I hope you submitted a solution to the
challenge I issued last month. I haven't
had time to receive any submissions yet;
it will take two or three months before I
can tell you of the results. This month
you will have plenty to do just entering
the source code data table.
The Character Set
The character set is just a big table
of data that the program can
refer to when it has to display a
character on the screen.
Many schemes have been worked out
to store such a table. The one presented
here takes only half the space normally
reserved but the program has to be just
slightly larger and slower. It is a matter
of sacrificing a few thousandths of a
second to save hundreds of bytes.
Why 51 x 24? The answer lies in the
size of the hires screen. The screen is 256
dots across so if each character is 4 dots
wide and we put one blank dot between
each letter then each character is 5 dots
wide. Doing a bit of arithmetic gives
256/5=51.2. With that character
width, only one dot is wasted. Then, the
252
THE RAINBOW
December 1984
screen is 1 92 dots high. If each character
is seven dots high, and one dot is used to
separate each line, then each character
is eight dots high. Some more arith-
metic gives 192/8=24 so no dots are
wasted.
Each character then can be repre-
sented as a grid four wide and eight
deep, or 32 pixels which fit neatly into
four bytes. Pretend we are going to fig-
ure out the data needed to represent the
"<" symbol. First draw a 4 x 8 grid and
shade in the symbol. The grid should
now look like Figure I. Using what we
taught you in lesson one (Aug. 84) turn
each one of those lines into a single hex-
adecimal digit (shaded =0, white= I ) and
write the digit next to the line it repre-
sents. The picture should now look like
Figure 2. Each pair of digits can now be
put into a single byte and you end up
with a list of lour bytes that looks like
this, ED B7 BD EF. In more technical
terms, each nibble represents a line. You
get two lines to a byte or eight lines in
four bytes.
Now type in Listing I. Remember to
save it as we will be adding to it over the
next several months. Assemble it and
save the output to tape or disk. To see
what you did, go to basic and type in
Listing 2. With the output of Listing 1 in
memory, run Listing 2.

This is the final installment of a series on creat-
ing a disk mailing list program
Developing A
Database Manager
By Bill Nolan
Rainbow Contributing Editor
For several months now we have
been exploring direct access disk
files on the Color Computer, and
we have been examining their use in a
simple database manager program. In
this column we have been working on a
mailing list program that is as complete
as some commercial offerings. The pro-
gram is written in a modular style, with
each section being testable separately.
That way we can add a section each
month and test it as though it were a
small program by itself.
If you have been following the column
you know that we have written all of the
program except the sort section, and
that will be added this month. If you
have been typing in the program as we
go along, the only lines you will need to
type from this month's listing are those
from 2000 to 2520.
Sorting is one of the most thorny
problems to face database programmers
on the Color Computer, and the reason
for this is the limited amount of memory
available on the machine. There are two
ways to sort a disk file. You can sort it
(Bill Nolan, who leaches "Pro-
gramming In BASIC "at the college
level, owns Prickly- Pear Software
Co. and has written several com-
mercially successful software
packages.)
on the disk, or in memory.
Sorting in memory is the fastest way,
but to do this you must have the entire
file in memory all at once. Since each
record in our file is about 100 bytes
long, we can only fit 10 records per I K
of memory into the machine. Since we
must have room in memory for our data-
base program and the computer ROMs,
and since we still need our screen memory
and disk buffer space, we are limited to
files containing only 100 or 150 records
if we want to sort in memory. If our
record length were longer, the number
of records we could handle is even
fewer.
If we choose to sort on the disk, then
the number of records we can handle is
limited only by the disk space, but we
have a dramatic loss of speed. The sim-
ple method of sorting on the disk is to
read two records into memory and
compare them to see if they are in the
proper order. If they are out of order,
we exchange them and then write them
back to the disk. Then the next pair of
records is compared. This is called a
bubble sort, and the other sorting
methods are not that different. These
methods use a great deal of disk access
time, and are slow, and using machine
language doesn't help very much, as
machine language makes no difference
in the disk access time.
We have a report from a man who
had a very nice commercial database
program, written in machine language,
and he had about 800 records in his file.
He told the program to sort them, and
the drive started running. Over 30 hours
later he turned the computer off. and
the drive was still running!
There is a third choice in sorting, and
it is a combination of the two
methods above. What we will do is read
only a part of each record into memory
the field we are sorting on. Then we
will do the faster in-memory sort on just
this part, compiling a directory of the
record numbers in the order we want
them. Then, after the in-memory por-
tion of the sort is complete, we will
create a new file named TEMP. DAT
and read the records from the first file in
the new order, putting them into the
new file. Then we will kill the first file
and rename the new file to the original
name.
This sounds more complicated than it
really is, as you will see, and with this
method we will be able to sort a file of
up to 400 records, and the sort will take
minutes instead of hours. Let's start by
looking at this section of the program
line by line, starting at Line 2000.
Line 2000 clears the screen and asks
the user which field they want used as
the basis of the sort. For instance, you
may want your file in alphabetical order
256
THE RAINBOW DecemDer 1984
by name, in ZIP code order, arranged
state by state, and so on. The subroutine
in Line 6500 is used to get the choice of
field. Let's suppose that the user chose
to sort by name (field 1 ).
Line 2010 prints the message "SORT-
ING..." on the screen and goes to the
subroutine at 5500 to open our file.
Lines 2020 to 2040 form a loop that
GETs each record from our file and
stores the record number in the numeric
array ST. At the same time, it stores the
field we want to sort on in the string
array 575.
Lines 2050 to 2070 are the actual in-
memory bubble sort (along with the
subroutine at Lines 2500-2520). Line
2050 opens the loop. Line 2060 com-
pares the two items, and if they are out
of order, it goes to the subroutine at
2500. The subroutine at 2500 switches
the position of the two items in the
string array ST$, and also switches the
corresponding record numbers in the
array 57", as otherwise the record num-
bers would no longer be associated with
the correct records. Line 2500 also sets a
flag, FL, to indicate that the swap has
been made. Line 2070 then closes the
loop and checks the flag. If it is set the
program goes back to 2050 and starts
the process over. This continues until a
complete pass is made through the
arrays with no swaps being made, and
Line 2080 then closes the file.
Lines 2050 to 2070 and the subroutine
at lines 2500 to 2510 could be replaced
by a machine language sorting routine if
you have the inclination (and the skill).
There have been routines like this pub-
lished in RAINBOW, and some are com-
mercially available.
Once the sort in these lines is com-
plete, the items in the string array
575 will be in proper order, and the
numeric array 57" will contain all of the
record numbers, also in proper order.
The lines from 2100 to 2150 now read
each record from the original file (in the
order indicated in the array ST), and
write them to the new file, TEMP. DA T
Line 21 30 checks to see if the field con-
tains an up arrow.
This requires a little explanation.
When we use the delete option during a
search, the delete section at Line 3180
fills the record with up arrows. This
symbol was used because, to the compu-
ter, an up arrow comes after all of the
letters and numbers in alphabetical
order. Thus, when a file is sorted, all of
the deletes are moved to the end of the
file. By checking for them, we can elimi-
nate the deletes from the file completely
and compress the file.
The loop that starts in 2120 and goes
to 2 1 50 will continue until all the records
have been moved to the temporary file,
or until a deleted record is found. When
either of these happens, the sort is com-
plete, and Line 2200 kills the unsorted
file, renames the TEMP. DA 7" file to the
original name, and returns to the main
menu.
By the way, if you want a double sort,
such as a file in ZIP code order that is
also in alphabetical order by names
within each ZIP code, just sort twice
— once on each field. In the example of
names and zip codes, sort by names, and
then sort again by ZIP code.
As we have been developing the pro-
gram, the operation of each section has

ter, and the reason for this
is the limited amount of
memory available on the
machine."
been explained in detail, but these are
all in different issues of I HE RAINBOW.
Now we will give some brief operating
instructions all in one place.
When you RUN the program, you
will first be asked for the name of the file
you want to work on. You can create
different files under different names if
you want to do so. If it is a new file, the
program will tell you, and then it will
ask you whether you want labels printed
last name first or first name first. When
you have indicated your preference, you
will see the main menu. You have five
choices on this menu, with the last being
"end the program." Since that is self-
explanatory, we will look at the "add
records" option.
You will be asked for the name,
address, city, state, ZIP code, and tele-
phone number of each record you add.
When you enter the name, remember to
type the last name, then a comma, and
the first name and middle name or
initial. If there is a title that goes after

the last name, put it before the comma.
Do not put more than one comma in a
record (you don't need any for business
names). It should be done like this:
Nolan, William
Anderson M.D., Thomas J.
Norton's Office Supply
Jamison. Rev. Mary
The other thing to remember is to use
the two-letter abbreviation for the state.
When you are finished adding records,
answer no to the question "want to add
more?"and you will be back at the main
menu.
The second choice on the main menu
is the sort section, which we covered
above, so we will go on to number three
— the search section. Here you will be
asked if you want matches to go to the
printerautomatically. Ifyouansweryes
to this, all matches will go to labels, and
you can go away and let the program
run. You will be asked for the field you
want to search and what you are look-
ing for. Partial matches will be found.
For example, if you choose to search for
names, and you search for "Robert,"
then Robert Smith, Janet Robertson,
and Mike Roberts would all be matches.
If you didn't send the matches to the
printer automatically, then every time a
match is found the record will be printed
on the screen and you will be given sev-
eral options. "Print label" will do just
that (be sure the printer is ready). "Next
item" will continue the search, "Return
to the main menu" will abort the search,
and "Delete" and "Change" will let you
delete or change the record on the
screen.
The "Print records" option on the
main menu is the other option with lots
of choices. You will be asked whether
you want to print on the screen, print on
labels, print on the printer (on paper),
or print a phone number list. These are
mostly self-explanatory, so just choose
the one you want. If you choose labels,
the phone number will not be printed,
and if you choose a phone number list,
only the names and phone numbers will
be printed on the printer.
Well, that about does it as far as
instructions are concerned, and this was
the last in the series about direct access
disk files. Next month we will start with
a new series of articles about the many
string handling functions available on
the Color Computer. You arc fortunate
to have a very complete and powerful
set of these functions on your computer,
and we will explore them in depth. The
articles will focus on one or two func-
tions each month, and we will include
lots of examples and some very useful
programs and routines. Have a happy
and safe holiday season!

EDUCATION OVERVIEW
Are Computers Producing
Unrealistic Expectations?
By Michael Plog, Ph.D
Rainbow Contributing: Editor
I recently saw an advertisement on
television that bothered me a great
deal. A concerned mother was dis-
cussing her child with a teacher. The
child was not doing well at all in school.
For the first half of the advertisement, I
thought it might have been produced by
the Mormons. (One of those extremely
well done "get in touch with your child"
spots.)Then, out of nowhere, the teacher
suggests to the mother that a computer
might help the child with her work. The
next scene shows a young girl waiting at
home. She is very unhappy, waiting for
the results of the parent / teacher confer-
ence to determine her future. Mother
comes in and says to the girl that they
are going to buy a computer. A change
comes over the girl; she smiles and hugs
her mother, content that she will now be
a success in school.
The ad bothered me a lot. It is true
that the Pennsylvania state education
department conducted a study and con-
( Michael Plog received his Ph. D. degree
from the University of Illinois. He has
taught social studies in high school,
worked in a central of/ice of a school
district, and currently is employed at the
Illinois State Board of Education.)
eluded that using computers in the
classroom improves student learning
and contributes to teacher efficiency.
Also, a study from New York Univer-
sity found that a significant number of
home computers were bought with a
primary purpose of education. The inter-
est in educational uses of computers is
growing as the evidence of effectiveness
mounts. What bothered me about the
advertisement is the development of un-
realistic expectations. A computer at
"The interest in educa-
tional uses of computers is
growing as the evidence of
effectiveness mounts."
home is not a guarantee of school
success.
Return for a moment to the study
conducted by New York University.
The principal researcher of this study
was Joseph Giacquinta, professor of
educational sociology. For three months.
doctoral students observed 20 families
in the New York area. They compiled
about 2.000 pages of log reports. That is
an impressive amount of information
for a case study, and this study may be
the first in-depth look at use and effects
of microcomputers in the home.
The primary activity for the families
using microcomputers for education was
programming, or learning how to pro-
gram. A "distant second" activity was
word processing -- school papers or
class notes. Only a few families used
educational software prepared by pro-
fessionals to learn school subjects and
skills.
The researchers of this study found
that parents believed programming
would make a person more logical or
rational. Also, programming was being
stressed in the schools their children
attended.
Unfortunately, learning to program a
computer does not make people more
logical. It simple makes them better
programmers. So far as I know, there is
no evidence that programming skills
transfer to other (i.e. .logical) skills: any
more than learning Latin makes a per-
son more disciplined and logical. (Are
you old enough to remember that as-
sumption by educators?)
December 1984
THE RAINBOW

If students are learning programming
in their schools, then practicing on a
borne computer can do nothing hut help
their school work but only that por-
tion of their school work related to pro-
gramming computers. Learning to pro-
gram a computer will not improve a
student's knowledge ol history (or biol-
ogy, or geography, or literature).
Please do not misunderstand me. I
personally favor students learning com-
puter programming. It is a skill that can
be uselul lor many purposes throughout
life. I know teachers who reduce their
homework (yes, teachers have home-
work also) by putting student records
on computers. Many service clubs and
associations now have members who
keep records on a microcomputer. Un-
told churches keep massive amounts of
member information on a microcompu-
ter. An uncountable number of profes-
sionals use their home computers for
office work. And with all this, we have
not even touched on the self-improve-
ment possibilities ol computer uses in
hobbies and personal interests. But.
learning to program a computer will not
make a person a belter reader unless.
of course, the programming results in
software for reading.
Well, why are these parents in New
York not buying more professionally
prepared educational software? The
researchers found the parents thought
the materials were inadequate. Other
factors were also noted by the research-
ers. Parents may not be aware of exist-
ing programs; they (parents) may lack
the skill to evaluate programs; the cost
of educational software may be too
high; and parents may not know how
the programs could be used by their
children.
The preliminary findings from this
study indicate that parents see the com-
puter as an important educational tool
for their children. The families, how-
ever, need additional help in under-
standing how the computer can be used
lor learning.
The parents in this study (as parents
everywhere, probably) wanted to im-
prove achievement at school and help
their children compete against others at
school, college, and at work. Parents
feared, however, that their children
would get "hooked on computers" and
neglect other important interests.
Mr. Giacquinta and his graduate stu-
dents will continue working with the
families in the study, and hope to expand
the research to a regional study, involv-
ing about 45 schools and hundreds of
families. I hope they obtain the neces-
sary funds for this research. The educa-
tional community needs the type of
information uncovered by this research.
We need the information to plan and
develop computer curriculum, to un-
derstand what is happening when stu-
dents interact with machines, and to
help build the educational experiences
that will be required in the next century.
Let's go back for a bit now, to the
advertisement noted at the beginning of
this article. The problem is unrealistic
expectations. Computer salespeople hold
up hardware and software as the cure
for everything from stupidity to warts.
When these claims are discounted by
the general public, the danger is that
real benefits of computers for education
will also be discounted. We need to
know what the computer will do. and
what it will not do. The process of find-
ing out what can and cannot be done by
computers is education. Let's keep on
getting educated.

Color Monitors Work Better
Than TVs,
Especially In Word Processing
By Dan Downard
Rainbow Contributing Editor
• / am interested in your comments con-
cerning the use of color monitors with the
CoCo. As you are aware, there have been
quite a few advertisements for color moni-
tors and video adaptors for the CoCo ap-
pearing in THE RAINBOW, After investigating
these color monitors, I find that all of them
appear to have low resolution. My question
is whether or not you gain anything by using
these color monitors with the CoCo instead
of a good quality color TV. which you may
have in your home at the present time. I read
an article in a current magazine which stated
that those color monitors were only good for
graphics. Since I use my CoCo for word
processing. I would appreciate your com-
ments on the video display these monitors
present when used with the CoCo.
Joe H. Apple
Walkerville. MD
How come Joe Apple has a Color Compu-
ter? He has excellent taste. I guess.
Joe, the limiting factor on the use of a
monitor is, "in fact, the CoCo. The 6847
Video Display Generator was designed for
use with an RF interface for driving a color
TV. You are correct in your assumption that
a "good quality TV "should work as well as a
monitor. I am using a Sony 1 3" color TV for
color graphics, but still use a 1 2" monitor for
word processing.
The problem with TVs is that R F interfer-
ence is always present and almost impossible
to completely eliminate. This fact, coupled
with the fact that most TVs do not have a

neer and has been involved in elec-
tronics for 24 years through ham
radio [K4KWT\. His interest in com-
puters began about live years ago and
he has built several 68 XX systems.)
sufficiently high bandwidth to display a 256
x 192 pixel dot matrix pattern, makes the use
of a monitor very appealing for word pro-
cessing.
I am convinced that the CoCo is compar-
able with any other computer in its price
range as far as graphics capability, but you
would never know it on a regular color TV.
IT'S ALL IN THE RESPONSE TIMES
• I'm amazed by your knowledge of the
inside operation of the CoCo! I have a good
question for you and hope you can help me!
In your October 1984 column, you told a
fellow CoCo user how to dump ROM packs
to tape, then to disk. I went to work, and
dumped my Color Baseball ROM pack to
disk. I couldn 't believe it — it worked!
Is it possible to play a Hi- Res game like
Color Baseball over the phone using a
modem? I use my driver program from my
Colorama BBS. The transmitting data LED
on my Modem 11 lights up to indicate that
something is being transmitted! On the
receiving end, the other CoCo is running
Colorcom/ E Version 2.4. He only gels gar-
bage characters from my CoCo. We've tried
changing the Colorcom parameters, but the
same thing happens. What would happen if
we both ran the program called Remote RM
from the November 1983 issue? I feel it
should be possible, but any advice you could
offer us would be great. Thanks, and keep up
the great technical work!
Dale Westmoreland
Lannon, Wl
I don't think it is practical to play action
games over a modem. Dale. The problem is
response time, not the transmission of
graphics information. When usinga modem
you are limited to 300 Baud operation, and
sending even one character requires a con-
siderable amount of lime. At the same time if
the game program was resident in both
computers, the key codes could be transmit-
ted to allow both players control of the
game.
Several different ideas come to mind.
First of all, try purchasing a program called
Graphicom. This program allows the trans-
mission of Hi-Res screens over a modem.
You will be able to transmit any graphics
screens available on the CoCo.
Another thought would be to experiment
with OS-9. or BASIC09. With BAS1C09 the
graphics module is controlled by an escape
sequence from the programmer. It is initialed
by the DISPLAY command. This makes
BASIC09 ideally suited for the remote trans-
mission ol graphics information, since just a
few characters arc all that is necessary to
control a graphics design. Good luck!
NOT THAT BALD
• My wife has given me an Apple Imagewri-
ter serial printer to use with my 64 K CoCo 2.
I built an interface using diagrams of the two
serial ports as found in the manuals. It works
beautifully at 9600 Baud in basic (POKE
I50.IJ. Using OS-9, though, when 1 set the
Baudot 9600 (xmode /p Baud=6). the print-
er puts out only garbage. When I change the
DIP switch settings to 2400 Baud and type
"xmode /p Baud=4", it does Just fine.
Do you have any ideas as to why I can 't get
9600 Baud in OS-9, when I can in basic?
Fred Saw telle
Huntsville, TX
Unfortunately, Fred. OS-9 is designed lor
use with an ACI A chip for serial I/O rather
than the PIA chip used in the CoCo.
268
THE RAINBOW
December 1984
ACIA stands for Asynchronous Com-
munications Interface Adapter and is a
device lhal receives parallel daia from the
internal CoCo data bus and converls Ihe
data to a serial output stream. The ACIA
takes care of all the timing loops required to
send the character. In the meantime the
microprocessor can perform a myriad of
other tasks required due to the multitasking
nature of OS-9.
I'lA is the notation for Peripheral Inter-
face Adapter and is the parallel output
equivalent of an ACIA. A PIA is designed
for the input; output of parallel data, and
therefore does not have all of the timing
circuitry necessitated by serial data. To send
a serial stream of information on a parallel
device the microprocessor must provide the
timing loops necessary. This is the reason
that you are having problems.
Dale Puckett's column. "Kissable OS-9."
contained a new interrupt driven driver lor
the serial port in the May 1984. RAINBOW.
This driver could be modified for a solution
to your problem. Fred, but 2400 Baud
sounds pretty last to me.
HOT CHIPS
• / have a 64K ECB CoCo I. I have been
having a problem with my right joystick fire
button for a long time. Please don 't tell me to
check the joystick — that was the first thing I
checked.
My problem is that the fire button will
stop work ing after the computer has been on
for an hour or more. Sometimes, but not
often, it won't work on power-up.
Once it stops work ing, I can usually find a
key on the keyboard which will act as the fire
button until it 'cycles' back to life.
I have checked the contacts in the joystick
plug as well as the computer 's. In reading the
technical manual and talking to people, I
think it is either LI. L2. or the PIA chip, but
I am no whiz at electronics. A ny clues? I will
be eternally in your debt if you can solve my
problem.
David Johnston
Orlando. FL
On an "F" board CoCo. David, the fire
button inputs are connected to U 18. a 6822
PIA chip, in parallel with the keyboard. It
sounds like you have a chip healing up and
going bad. The right button is connected to
Pin 2 of U 18. 1 would replace UI8andseeif
this solves your problem.
INTERFACING TWO PROGRAMS
• I need some advice about the possibility of
having two machine language programs in
memory simultaneously. First of all, is it
possible? I have a 32 K CoCo with Extended
BASH and a cassette drive. I have the Musica
software from Speech Systems, and the
Voice Pak. from Spectrum Projects. I would
like to have the speech synthesizer announce
each song to be played. This means having
the text-to-speech software and the Musica
file in memory at the same time.
I would appreciate it if you could tell me if
this is possible, and if so, how to do it.
Bergen II. Woods
Bensalem. PA
Your problem is not having the two pro-
grams in memory at the same time Bergen,
but how to interface the two. You can have
as many machine language programs in
memory at the same time as memory per-
mits, as long as the locations do not overlap.
As I am not familiar with these particular
programs. I will not attempt to give you the
proper addresses.
Maybe a letter to Speech Systems can
identify the addresses of the output routines.
I'm sure you already have the addresses of
the Voice Pak input routines. Just call the
Voice Pak input routine with the output rou-
tine in the Musica. It may be a little compli-
cated since you are dealing with strings
instead of individual characters, but "Where
there's a will, there's a way."
text the tt-2 directs all output to the printer.
If you are into assembly language, the flag
at $6F must be set with the value -1 and the
output routine at SA000 must be called using
indirect addressing.
As far as printing the contents of the
screen, assuming you are using the normal
32 x 16 text mode, try the following screen
dump program. Insert it into your BASIC
program as a subroutine and call it using the
command GOSUB 10000 whenever you
wish a screen dump.
10000 ZZ=0
10010 FOR XX=I024 TO 1535
10020 YY=PEEK(XX):ZZ=ZZ+I

• What are the most common commands
on outputling a program from the screen to

procedures to use after the program is
typewritten on the screen. I am a novice in
operating the printer. Thanks very much for

Mark, as you may have guessed by in-
specting the screen dump program in this

located from 1024 to 1535 in memory, or
S400 to $5 FF. I don't see any reason why you
can't just poke your string into the proper
location without the screen scrolling.
At the same time, the pointer for the next
character to be printed on the screen is S88.
the cursor position. By subtracting S20 from
this value, you can keep the screen from
scrolling. You can actually move the cursor
anywhere on the screen. By a pointer I mean
a value in low memory (RAM) that is used to
keep track of what's happening.

OS-9
KISSableOS-9
Closer to UNIX
By Dale L. Puckett
Rainbow Contributing Editor
RAINBOWfest Princeton was
outstanding. It was also ex-
hausting. Yet, I have an intense
enthusiasm lor OS-9 and was happy to
have the opportunity to talk about it lor
an hour and a half. It was standing
room only; there must have been 300
people in the room. OS-9 is hot stuff.
In fact, OS-9 is so hot that RAINBOW
hopes to increase its coverage soon. We
especially need useful application pro-
grams that our readers can type in and
run. If you've written one, please get in
touch with Jim Reed. If you're applica-
tion is long, he may be able to serialize it
over several months. If you have short
hints, tips or short utilities please send
them to me and 1 will make every
(Dale L. Puckeli is a free-lance writer
and programmer who has worked with
the Motorola family of microprocessors
since 1976. He just completed his first
hook. The Official BASIC09 Tour Guide,
this summer. It has been published by
Microware and made its debut at the
Chicago RAINBOWtest. He is the au-
thor of DynaSpell, Readtest, Esther
and Help, which are available from
Frank Hogg Laboratories. He serves on
the Info World Software Review Board
and is a Chief Warrant Officer in the
U.S. Coast Guard.)
attempt to get them published here in
"KISSableOS-9."
Speaking of utilities published here,
congratulations to Tim Harris, a senior
in the computer science programs at
Iowa University in Ames. Tim has
shared several programs with you in
these pages (including two this month)
and donated several C and assembly
code listings for the Official RAINBOW
OS-9 Guide.
Harris wrote us last week to thank us
for publishing his work and to tell us
that his listings in RAINBOW and in our
new book helped him land a job at Mi-
croware in Des Moines. He said that
because of the experience he gained
writing utilities for RAINBOW and the
OS-9 Users Group software exchange
library, he would not have to start out
writing C utilities like most beginning
programmers. Thanks again for sharing
your work Tim, and the best of luck in
your new career at Microware.
Many of you have asked RAINBOW
for more information about OS-9. Bruce
Warner, president of the Northern Vir-
ginia Color Computer Club, will pres-
ent the first of a series of tutorials in the
January "beginners" issue.
Warner bought OS-9 at the local
Radio Shack store here in Virginia
shortly after it was released. Unfortu-
nately, he became frustrated and put it
back on the shelf. After I spoke to the
club Sept. I. I let him read our new
book. Before the week was out, he
started to understand OS-9 and now
uses it almost exclusively. He hopes to
share his "learning experiences" with
you.
New Tools Abound At RAINBOWfest
We had our ears filled in Princeton.
Third party software houses and inno-
vative manufacturers are striving to
keep the Color Computer the best bar-
gain for your computing dollar. Because
of efforts, the outlook for you couldn't
be brighter.
We talked at length with creative
people like Al Alberto at PBJ; John
Kun/e at RGS Micro Inc.; Brian Lanlz
at Computerware and FHL: and Joe
Turner at Computer Systems Center to
name just a few. They could barely con-
tain their enthusiasm.
Let's start with PBJ. They brought 20
of their new Word-Pak H 80-column
displays to RAINBOWfest but by the
time I returned to their booth to buy one
late Sunday, they had sold out. If you
were impressed with Word-Pak. you'll
love Word-Pak II.
PBJ's new cartridge brings you
smooth scrolling, which means you can
December 1984
THE RAINBOW
271
scroll the display oil the screen one pixel
at a time instead of an entire character
line at a time. The character set has also
been improved, and if you look closely
you'll find a full 8x10 matrix that sup-
ports nice looking characters with full
descenders.
The thing that really impressed me
about this new board was the software
switch that lets you display either
Word-Pak 's output or the video output
from your Color Computer. You can
now write a program that uses both 80-
column text and graphics.
Cbreeze From PBJ — A Screen Editor
For Programmers
And speaking of enthusiasm, Al
tally, John loaned me one of their hard
disks with the OS-9 drivers, so we hope
to give you a detailed report sometime
in the near future.
Brian Lantz. was excited, too. He flew
to Princeton from Tampa so he could
demonstrate some of his software at the
FHL booth. Frank welcomed the help.
He and his cousin Rich were busy with
NOMAD, the new robot Frank hopes
to sell for Christmas.
Lantz is the author of OS-9 Texlools
from Computerware and the Uni-
Charger from FHL. Textools is one of
the best utility packages for the Color
Computer OS-9 user because it is writ-
ten in assembly language. This makes
the package short and fast. Many of the
"... OS-9 is so hot that RAINBOW hopes to
increase its coverage soon. We especially need use-
ful application programs that our readers can type
in and run.''
couldn't wait to tell me about a new
software tool. Al recognized the need
for a short and last screen-oriented edi-
tor for OS-9. He teamed up with Steve
Bliss, and the result is Cbreeze.
I asked about that name and Al rep-
lied that it was a "breeze" to use and it
was written in c, hence the name
Cbreeze. We haven't had the time to test
drive Cbreeze yet, but are looking for-
ward to the experience. Despite the fact
that this editor is only a little more than
1 IK bytes long, it appears to be quite
comprehensive. All the standard cursor
controls and screen movements com-
mands are present, as is the ability to
pass a command to the OS-9 shell.
128K Cards Optimized For OS-9
John Knuze of RGS Micro Inc. was
so excited Sunday you couldn't hold
him down. He was showing off their 10
megabyte hard disk and describing the
software he is writing for the 128K
board. He is attempting to make the
paging operation completely transpar-
ent to the OS-9 user. I look forward to
seeing it.
After the exhibits closed Sunday,
John gathered all the I28K board manu-
facturers together and sat them down to
define a standard so that everyone's
hardware would be compatible. It's great
to see this kind of cooperation, lnciden-
other packages are written in C and use
quite a bit of your memory.
But the UniCharger is the real story.
We listed the names of the utilities in
this package several months ago. It's the
package that makes OS-9 look a whole
lot more like UNIX, bringing capabili-
ties like AT and MAIL to OS-9. Lantz
sent me a beta test copy several months
ago and I exercised most of the new
utilities.
I never did get around to installing a
few of the more sophisticated system
tools, however. To use them 1 would
have had to modify my system pass-
word file. Between the new book, two
RAINBOWfests, the Microware OS-9
Users Seminar and a major oil spill, I
just couldn't work it in. Besides, it
looked like it would be a hassle to do the
job by hand. And, since 1 believe that
my readers want software that is easy to
install and run, I hassled Brian.
A pleasant surprise awaited me in
Princeton. Lantz handed me a disk with
the production version of the Uni-
Charger. When 1 listed the directory, it
contained files named DO. Install and
HO. Install. They automatically copy all
the commands to your CMDS direc-
tory, create a "profile" file, as well as
MAIL and AT directories in your SYS
directory, and convert your password
file to the format needed by the Uni-
Charger utilities. All you have to do is
watch the computer do the work. That's
the way software should be sold.
But, 1 soon learned that the Uni-
Charger production disk was only a
beginning. Lantz proceeded to tell about
a new package he is preparing for FHL
that will enhance your business. Pro-
grams in the set include CALENDAR,
LN, DELN, LPR. LPQ and LPRM. If
you look in a UNIX manual you'll see
full descriptions of most of these new
OS-9 tools.
Calendar lets you print any informa-
tion about an activity you have sched-
uled for "today" or "tomorrow." It gets
this information from a file named
Calendar, which is stored in your SYS
directory. On the surface this may not
excite you. But, stop and think about
the rest of the UniCharger package for a
moment.
For example, you can use the AT
command to run Calendar early in the
morning. Calendar can run the MAIL
command to put its information in your
mailbox. When you come to work and
sign on to your OS-9 terminal, you'll be
reminded of that important meeting
you scheduled two months ago.
LN works like the UNIX LN or
ALIAS utilities. It gives you a way to
use a filename in your current data
directory to point to another file some-
where else. A file that has been linked to
another by LN is like a synonym in the
English language. The two filenames
mean the same thing. DELN is a special
version of the standard OS-9 DEL util-
ity that you must use to delete a file that
has been LNed.
LPR is an off-line printing utility that
performs exactly like its UNIX name-
sake. This command enters the name of
a file in the line printer queue and copies
it into the LPR directory. If nothing is
being printed from the queue, LPR pro-
ceeds to print it. LPQ reports the cur-
rent state of the line printer queue and
LPRM gives you a way to remove files
that you own from the line printer
queue. UNIX-like print spooling has
arrived on OS-9.
About DynaCalc And OS-9
Finally, we can tell you a little bit
about the hard work Joe Turner at
Computer Systems Center has been
doing for the Color Computer OS-9
owner. I say "finally" because we've
known about some of these projects for
more than six months. Unfortunately,
we couldn't tell you about them because
the news wasn't official.

Calc and Dynamite+ programs to FLEX
and OS-9 users with SS-50 buss systems
for several years. Both of these pro-
grams are nothing short of outstanding.
In fact, for about nine months now,
people who own the PBJ 80-column
card have bought DynaCak for their
Color Computer. It was a great combi-
nation.
Then, Radio Shack announced Dyna-
Cak running under Disk Extended
BASIC — complete with graphics. About
the same time we learned from Joe that
Radio Shack had licensed DynaCak for
OS-9 also. It's been released now, so we
can steer you toward this powerful
spreadsheet program.
Word Processing Utilities
The programs on disk three have
been chosen for their usefulness in word
processing. Here is a list of all the files
on this disk along with a short descrip-
tion.
tc is a program that does a line by line
comparison of two text files and prints
the lines that differ. It is written in Mi-
croware's C.
ppc paginates, dates, titles and lists C
programs and text files to OS-9's stand-
ard output path. It is also written in
Microware C.
split lets you compare two text files
visually. It lists them side-by-side on
your screen. You'll need a terminal or
"If you're looking for an outstanding- disassem-
bler that can help you with OS-9, FLEX and Disk
BASIC, check out the RAINBOW review in this issue.
You can learn a lot about assembly language pro-
gramming from disassemblers. "
DynaCak- was modeled after Visi-
Calc and runs most VisiCalc templates
nicely. But, DynaCak- has been enhanc-
ed to the point that it is much faster and
much easier to use than VisiCalc. If
you're a manager and need a spread-
sheet, give Joe Turner a call — or ask
about DynaCak- at your local Radio
Shack store.
While we're speaking of Joe, we should
remind you about Dynamite+. If you're
looking for an outstanding disassembler
that can help you with OS-9, FLEX and
Disk basic, check out the rainbow
review in this issue. You can learn a lot
about assembly language programming
from, disassemblers. In fact, the very
first program 1 wrote in assembly lan-
guage was a disassembler for the 6800
microprocessor. Without that project, I
probably would never have learned how
to program in assembly language.
User Group Library
In a recent column we announced the
availability of OS-9 Users Group disks
one through five, and described the
items on disks one and two in detail .
For those of you wondering about disk
three and beyond, here's what you can
expect. We're sharing this list because
the users group is a good source for
educational and useful programs. At $3
per disk of eight to 12 utilities, the price
is right.
80-column card for this one since it
shows the first 38 characters of each line
of both files at the same time.
unlub expands the tab characters in a
file to spaces. It assumes that the tab
stops are every eight columns.
lab converts the spaces in a text file to
a combination of tabs and spaces. It
reduces the size of a file.
Sqsh is short for squash. It com-
presses all strings of spaces down to one
space and replaces carriage returns with
a slash, "/"• Sqsh is written in 680?
assembly language.
TexCom is a BASIC09 program that
compares two text files one line at a
time.
Words. ASM splits a text file into
individual words and prints them one to
a line. It is written is 6809 assembly
language.
Translii is a BAS1C09 program that
implements the transliteration algorithm
described by Kirnighan and Plauger in
the book Software Tools. It, in effect,
translates a character or series of char-
acters in a file into another character or
series of characters.
Programming Utilities
Here is a description of the program-
ming utilities contained on User Group
disk number four.
ModBuild is a BASIC09 program that
gives you a way to build a file containing
more than one module from several sin-
gle or multi-module files. It is a perfect
tool for building a new OS9Boot file.
mv moves files from one directory to
another by manipulating pointer refer-
ences. No data is actually moved so it is
an extremely fast way to transport large
files from one directory to another.
latest scans a directory and all direc-
tories below it and prints the name of all
files whose last modified date and time
is later than the one you type on the
command line.
module can be used to pass only
selected modules from a file that con-
tains many modules. It reads from
standard input and writes to standard
output, passing only the modules you
name on the command line.
graft is similar to dsave except it
actually copies the files in a directory
instead of writing a shell procedure file
to do the job. It uses a 32K buffer.
Pwd source code will show you how
the print working directory command
works.
BinCom is a basiciw program that
does a byte for byte comparison of two
specilied files. It reports the differences
and then offsets into a file.
DCopy is a BASIC09 program that
copies the files in one OS-9 directory to
another directory.
File Processing Utilities
The programs on disk five have been
chosen for their utility as file processing
aids. Here is a list of all the files on disk
five:
stripz copies labels from a disassem-
bly file to a separate file to help you
create a substitution file with your edi-
tor. It is written in BASIC09.
equfix is a BASIC09 program that
strips comments, blank lines, and pseudo
opts from equate files.
pad improves the readability of your
disassembly files by inserting blank lines
after each statement that transfers con-
trol of the program. It is written in
BASIC09.
sort is a general purpose sort. The file
being sorted must fit in memory.
Hx prints each byte it reads from the
standard input path in hexadecimal on
the standard output path.
StripNum is a basiciw program that
strips a specific number of characters
from the beginning of each line in a text
file. One use would be to strip the offset
numbers out of a BASIC09 program list-
ing.
StripREM strips all REM statements
out of the specified input file. It is writ-
274

ten in BASIC09.
FlexBin converts FLEX formatted
binary files into full image binary files.
It writes a new file in the OS-9 file for-
mat.
NewSlrip strips all control characters
except carriage returns out of the stand-
ard input path.
extract filters single C function defini-
tions out of a C source file and sends
them to the standard output path.
patch lets you change selected bytes
in a data or directory file. It prompts for
the address to change and then displays
the value of the byte at the location you
request.
intruder is similar to the standard
OS-9 dump utility except that you can
dump selected sectors from a disk. When
called it displays the first sector of a file
and then asks you which sector you
want to see next.

The only other thing you need to do if
you are using double-sided drives is to
run D.P.Johnson's BOOTF1X on drive
You should see a listing similar to
this:
Volume - 'Rainbow-Articles' on device
/dl
S00B4 bytes in allocation map
I sector per cluster
S0005A0 total sectors on media
Sector $000002 is start of root direc-
tory FD
S000A sectors used for id. allocation
map and root directory
Building allocation map work file...
Checking allocation map file...
'RainbowArticles' file structure is
intact
4 directories
7 files
"You need a quick count of every file on the entire
disk, but you are afraid if it would take days to
trace all the directories. No problem, it's time to let
DCHECK go to work."
You'll notice that some of the mod-
ules saved by the Word-Pak II install. 2
/dl immediately after you use the
OS9Gen command. Just insert the fol-
lowing line in the procedure file after the
line that contains the OS9Gen command:
BOOTF1X /dO
An alternate method is to install
Word-Pak II as directed using a stand-
ard copy of Tandy's OS-9 and the origi-
nal Word-Pak //installation procedure.
After you have done this, you can install
the additional disk descriptors and the
new disk driver. In either case, once
Word-Pak II is installed, you will be
delighted with the results.
DCHECK
Sometimes you will find that you
cannot read a file. Yet, everything ap-
pears to be okay. You've checked to see
if the file is a directory file, it isn't.
You've checked to see if it is an execut-
able file, it isn't. What next?
One thing you can do is check the file
structure of your disk. If your only ex-
perience up to now has been with Color
Computer Disk Extended basic, you're
in for a treat. OS-9 gives you a com-
mand that you can only wish you had
with Disk basic! Enter DCHECK.
DCHECK lets you verify the file
structure of any disk mounted in any
drive on your system. Don't be confused
by the S0005A0 sector count. That's
1440 in decimal. 1 use 40-track, double-
sided, double-density drives.
If you are using a system with two
drives try entering DCHECK /dl.
Perhaps you've just developed a ser-
ious software package designed to count
the number of hairs on a balding head.
The disk containing your program and
its necessary modules and data files
includes a number of files that are
stored in several sub-directories. Since
your program is dedicated to counting,
you want to tell potential customers
exactly how many files and directories
are on the disk.
You need a quick count of every file
on the entire disk, but youarealraid if it
would take days to trace all the directo-
ries. No problem, it's time to let
DCHECK go to work. DCHECK has
an option that can give you the exact
information you need.
If your disk has as many sub-direc-
tories as the Tandy OS-9 System Disk,
you will find an unknown number of
files stored in an unknown number of
directories. Use the DCH ECK command
with the "-s" option and you should see
something like this:
4 directories
59 files
You may also want to use the "-b"
and "-p" DCHECK options, "-b" lets
you check the structure of a disk with-
out listing the unused clusters, "-p"
prints the complete pathlist to each clus-
ter that may have a problem.
You should note thai DCHECKcan-
not process a diskette with directories
more than 39 levels deep. Who cares?
December 1984 THE RAINBOW 277
How many limes are you going to wind
up at level 39 with single-sided. 35-track
drives? If you ever find yourself that far
out on a limb, you've probably over-
organized your directories.
Two Tips Born Of Necessitiy
One night this week, following a long,
hard evening filled with "writer's block"
and a general lack of creativity. I saved
my efforts and went to bed. The next
evening I tried to run a word count —
the wc utility — and came back with
zero words. Then, 1 tried to list my arti-
cle and OS-9 returned a CRC Error. I
tried to copy it to another file and got
the same result. I kept trying. Nothing
worked.
I didn't have the energy to rewrite
3.000 words. Further, I didn't have
lime. I had to find a way to recover my
work. 1 used a disk edit utility 1 own and
attempted to dump the sectors in the
bad file. It turned out that the first sec-
tor of the file contained garbage. OS-9
refused to read it. Since everything else
in the file seemed to be all right, the
answer was to skip the first sector. The
BASIC09 procedure below will do the job
for you.
PROCEDURE recover
(* A way to skip a bad sector *)
DIM char.path,newpath:BYTE
OPEN #path,"KISS.temp":READ
CREATE #newpath."KISS. recovered"
:WR!TE
SEEK #path,257
WHILE NOT(EOF(#path)) DO
GET #path,char
PUT tfncwpath.char
PUT#l,char ENDWHILE
END
You could also use the procedure
above if the bad sector in your file was
located in the middle of the file. To do
this, you could list the file to another
file. It should work up to the point
where you hit the bad sector. At this
point you can count the number of bytes
you have recovered, add 256 to it and
change the SEEK statement in the pro-
cedure recover to get you past the bad
sector. Then, merge the two files to-
gether and rewrite the copy that was
held by the bad sector. Rewriting 256
characters is a whole lot better than
rewriting 3.000 words. Good luck.
A DynaStar Tip
Since 1 got behind while writing the
new book and attending the RAIN-
BOWfest, 1 did some of this column on
my Radio Shack Model 100 while rid-
ing in the carpool.
However, when I uploaded the file
from the Model 100 I found that it left
the TAB character, 9 decimal, in the file.
At other times, I've needed to remove
line feeds. For example, I often dupli-
cate the output of a DIR command in
the column. The DIR command sends
out a line feed. 10 decimal or S0A hex-
adecimal, after the header.
These extra characters drive Dyna-
Star's cursor control bonkers. In fact,
they may do the same to your screen
editor. The solution is to use a TR or
transliterate utility. One is available
from the Users Group Software Com-
mittee, another is in the OS-9 File
•With OS-9, you al-
most don't need to create
it. The capability is built
in.
Handlers Toolbox from Microware.
Here's the command line I used.
OS9: list KISS. temp ! tr \9 ! tr \I0
>K1SS. December
Emulating A Typewriter
On my desk at work, 1 use a Wang
PC. I didn't buy it. Frankly. I would
rather use DynaStar or Stylo than the
archaic, memory hungry, menu-driven
monster word processing software in
the PC. However, it has one function 1
like a lot — it can emulate a typewriter.
Needless to say, you must get through
two or three menus before you can use
it, but, it really comes in handy for short
notes and memos when you don't want
to bother to go through three menus to
create a new word processing docu-
ment. I decided 1 would create this func-
tion for my G1MIX and Color Compu-
ters.
With OS-9, you almost don't need to
create it. The capability is built in.
However, I want to take you through an
experiment that will help you under-
stand a few of the OS-9 commands and
a BASico 1 ) procedure that shows how
you can use more than one technique to
do a job.
First, let's try to build a typewriter
emulation with the copy command. It
should work, shouldn't it? Try the
command line below. Type the ESCAPE
character CLEAR BREAK on Color
Computer OS-9 when you get ready to
quit.
OS9: copy /term /p
What happened? I'll bet it worked
great on the first line you typed. You
were probably even wearing a broad
smile until you typed the second line. It
was printed right on top of the first line,
wasn't it?
This happens because the copy com-
mand does not use the built-in OS-9 line
editing functions. It uses character in-
put/output rather than line input and
output. As any hacker will tell you. it
uses the ISRead and ISWrite system
calls rather than the ISReadLn and
lSWritLn calls.
Let's try again. Type:
OS9: list /term>/p
It worked, didn't it? Congratulations,
you now own an extra typewriter — and
one that will let you edit or correct each
line before you print it. Experiment a
little and you will find that the CLEAR
A, CLEAR X and other OS-9 special
line edit keys all work while you are
using this command line.
1 was disappointed. I wanted to write
a BASIC09 program to do the job. In fact,
I wrote it anyway. It will show you how
certain high level language functions
relate to functions at the Operating Sys-
tem level.
PROCEDURE tw
(* Emulate a typewriter *)
DIM printer:INTEGER
DIM in:STRING[80]
OPEN Sprinter,"/ p": WRITE
LOOP
ON ERROR GOTO 10
INPUT "Enter: ".in
WRITE tfprinter.in
ENDLOOP
10 CLOSE tfprinter
END
When you test "tw" you'll see that it
works just like the OS-9 command line
that used the LI STcommnnd. But since

you now have it in a high level language
you could add some fancy features of
your own. If 1 get a chance, we may
pursue this further in the future. In fact,
if you add some bells and whistles I
hope you will share it with other"KlSS-
able OS-9" readers. Here's a hint from
The Official BASIC09 Tour Guide.
Study the procedure CONVERT on
Page 75. Have fun!
D UTILITY — DIRECTORY
The "d" utility is a new directory
command similar to "Is" in UNIX,
which prints files in the current data
directory to standard output. The files
are listed one per line instead of several
per line as in the usual dir command in
OS-9. This feature allows the output of
d to be used by other utilities, like dl and
wc. d also includes a wild card option so
you can output only files with certain
characteristic patterns.
The d command has two options
only, -? and -w. The -? will output a help
message and the -w will turn on the wild
card matching for the command. There
are two wildcard characters that can be
used, '? and *.
The question mark is a single charac-
ter wildcard while the asterisk is a mul-
tiple character wildcard. For example.
a?c matches "abc". "adc","aec",etc... You
can use the ? wildcard also to match
only files of a given length, for example.
???? matches names with four charac-
ters, ??? matches names with three char-
acters only, etc.
The asterisk wildcard can be used in
three ways basically, in the front as in
*.c it matches any names ending in ".c";
in the back as in ab* it matches any
names beginning in "ab" and in the
middle as in *a* it matches any names
with an "a" in the middle.
Some sample calls with just the d
command are:
d lists all the current
directory
d -w *.c lists files ending in ".c"
d -w c* lists files beginning with "c"
d -w a?c lists files "abc'V'adc"
d -w TV. lists files with three char
names
d -? prints help message
The d utility can also be used with
other utilities, especially, dl. With dl
you can pipe the d output to delete a list
of files, using the -z option of dl. In this
way you can delete all files in a directory
with one line or delete all files matching
a given pattern with a one line com-
mand.
Example calls with dl are:
d ! dl -i deletes all files in current
directory
d -w *.c
! dl -z deletes all files ending in
".c"
d -w ?? !
dl -z deletes all files with 2 char
names
You could also use d with other utili-
ties in the package to get other results.
For example, piping the output into wc
will give the count of files in the direc-
tory:
d ! wc -1 prints count of files in
directory
d -w *.c
! wc -1 prints count of all ".c" files
DL UTILITY - DELETE
The dl utility is a delete utility similar
to the delete command found in OS-
9/68K. It can work just like the stand-
ard OS-9/6809 command or it can be
used as discussed in the previous section
with the d utility.
dl contains only two options also; -?
to generate a help message and -z to
allow a list of pathnames to be used
from the standard input, thus making
the facility for piping into dl via d.
To use like the standard command
you use a command like:
dlfilel [file2] ... [filen]
You can delete as many files as you
can fit in a command line.
To use dl with piped input on stand-
ard input you must use the -z option.
With this option a list of filenames to
delete is read from the standard input
path instead of from the command line
itself. Examples for this command were
given above.
That's about it for December. I hope
you will find the tips and utilities useful
and willjoin us in 1985 for more"KlSS-
able OS-9" tidbits. Until then, have a
pleasant holiday season. May your
stocking be filled with new OS-9 soft-
ware.

128K And FLEX
By Frank Hogg
Rainbow Contributing Editor
In a companion article, Dennis
Lewandowski shows how you can
add 64K to your CoCo to bring the
memory up to I28K. Now the question
is what to do with it. Of course, it would
be nice to be able to use this with FLEX
and OS-9, but there is a problem with
OS-9 that is too complex to go into
here. However, it is easy to use it with
FLEX. In this column. I am going to
discuss some thoughts on how this
could be done, and next time 1 will pro-
vide a program to do it. 1 understand
that Dennis' company, DSL, is doing a
RAM Disk for FLEX.
Figure 1
:ROM :. : RAM : Upper 32K
::x::
: RAM:: RAM::' RAM i Lower 32K
: ;: 1 ;: 2 \
Figure I shows how the 128K is
mapped into the system. Keeping in
mind that the 6809 can only work with
(Frank Hogg is the president of Frank
Hogg Laboratory, one of the world's
largest suppliers of software for 6809
based computers. He and his wife,
Linda, live in Syracuse. New York.)
64K at any one moment, we see that we
can have either ROM or RAM in the
upper 32K, which is nothing new. but
we can now have any one of three 32K
banks in the lower 32K. Both FLEX
and OS-9 work by running the CoCo in
the all-RAM mode where the upper
32K is RAM and the lower 32K is
RAM. OS-9 uses memory in a very
complex and rather slick way. While it
is possible for OS-9 Level 11 to address
more than 64K. it is done in a much
more elegant way than we have here.
The main shortcoming is that systems
(Gimix, etc.) that support OS-9 Level 11
have hardware that allows the memory
to be broken into 2K or 4K segments.
The system puts these chunks together
in various different physical pieces that
look to the 6809 as a contiguous block
of memory. OS-9 Level II has been
designed to work with this type of fancy
hardware. About the only thing that
could be done that would be useful
would be a memory disk for OS-9. This
would also be handy for FLEX and is
what Dennis is working on. but there is
a simple way to implement the other
two 32K banks or RAM with FLEX.
First the limitations: FLEX has a
total of 46K user memory that is ad-
dressed from $0000 to SB7FF. We can
switch the lower 32K, S0000 to S7FFF
between the three different banks, but
the memory from S8000 to SB7FF is
part of the upper 32K of RAM that
cannot be switched.
Doing It In XBASIC
It would be nice to have several
Extended BASIC programs running that
could switch from one to the other. The
problem is that TSCs XBASIC uses all
of the user memory and puts its stack at
the top of user memory. A way around
this would be to move MEMEND to
S7FFF. which would allow switching
without creaming XBASIC's stack.
However, there are complexities in-
volved with this. First, consider the
state of Extended BASIC when the switch
is made. If you did it by using POKEs,
then you would jump from one running
BASIC program into who knows where
in another BASIC program. If you did it
with an EXEC command from BASIC,
you would have to preserve the return
address stored in FLEX for the bank
you were in and set up the return
address for the bank you were jumping
into. This whole thing is fraught with
peril. However, it would provide an
almost endless variety of ways to crash
the system. A considerable amount of
thought needs to go into this aspect of
using the extra memory. This will be
part of next month's article.
Another way that would be very easy
to implement, and would be fairly safe,
would be to simply LOAD programs
that you are going to use into the differ-

ent banks, and then just switch to the
bank and jump to the warm start address
of the program to use it. This could be
called the poor man's virtual disk, and it
does fit into a magazine article very
nicely.
Let's look at the problems of doing
this. Loading a program into memory is
simple: you just GET it, as GET
O.ED.CMD. Now, you can't just jump
to the program's start address, because
it will tell you it needs a filename to edit.
Most FLEX programs get their file-
names from the command line. The
sequence ED TEST first loads ED, and
then ED runs, and the first thing it does
is to look at the command line to get the
filename of TEST. If we had ED in
memory, and we knew its start address
was $0100, we could just type JUMP
100 TEST. The JUMPcommand resides
at SC100 and, therefore, will not crash
ED. In order to use this with the 128K,
we need to switch to the bank with ED
in memory and then jump to the start
address with a filename on the com-
mand line. We need a command that we
will call BANK, which takes two argu-
ments. The first is the bank to jump to
and the second is the address to transfer.
BANK with no arguments should return
the bank we are currently in, in case we
get lost in memory. The piece de resist-
ance would be to make BANK memory
resident so we would not have to access
the disk every time we used it.
There is a block of memory at SFE00
that is not used by FLEX. It is 256 bytes
long. We can write a program that will
patch itself into the user command table
and reside at SFE00 and do all the
things we want to do. We could even try
to preserve the warm start return address
for each bank for possible use by BASIC.
While you are waiting for the next
issue of THE rainbow for this program,
you can play with the concept by using
the MON command to switch banks
and the GET and JUMP commands to
try it out.
This would be very useful to the
assembly language programmer. Writ-
ing assembly language is fun, but it can
be a pain. After you test your program,
you usually have to make a small cor-
rection, then reassemble it and test it
again. This series of ED, ASM, TEST.
ED, ASM, TEST etc.. is a nuisance.
With three banks to work with, we
could load one with ED, one with ASM,
and use the third fortesting. Even doing
basic programming, we could load one
bank with BASIC and the other with ED
and use the powerful editor instead of
the one in BASIC. This technique could
be used for any language development.
The one key thing you need to know
is the cold start address of the programs
you wish to use this way. You can find
this by using the MAP command that is
available with Ed/Asm or some other
utilities, or you could refer to Figure 2
which has a listing of addresses for var-
ious popular programs. Caution: I have
not had time to test any of these because
of the magazine's deadline, so I will
leave the fun part to you.

128K Another Way
After I started this article, 1 received a
I28K board from RGS Micro. Their
128K board for the CoCo is similar to
the DSL board but appears to have
some additional capabilities. The two
approaches are different. The DSL
approach is one that you can do your-
self for the least amount of money. The
RGS board is more expensive but may
be easier for the faint of heart. 1 would
like to go into a good comparative
review, but 1 didn't have the time to do it
before this deadline. 1 can say that from
what I've seen so far, I don't think you
would be unhappy with either choice.
Both techniques offer 128K. both will
work with FLEX, and both will work
with OS-9 as a RAM disk. I don't think
that either will work like OS-9 Level II.
but that is just my opinion. There are
some pretty clever programmers that
have surprised me in the past. I can say
with some confidence that it won't be
easy to get it to run like Level II. After
all, it took Microware one year to get
from Level I to II, and they had the
source! However, a 64K RAM disk
would be very useful in OS-9. FLEX or
Disk BASIC.
Problems
The 128K boards remind me of when
you had to modify your computer to get
to 64K. In order to use I28K you will
have to open your computer and break
Radio Shack's precious seal. Well, if
your computer is out of warranty, then
there is nothing to lose. Some people
think that they will have trouble trying
to get their computer fixed at Radio
Shack if they have modified it. This is
probably true if the modification inter-
feres with repairing the computer. If
you fall into this category, then you
should be prepared to remove any mod-
ifications before you return your com-
puter to Radio Shack for repair. With
this in mind, consider how you will
accomplish the upgrade to I28K in a
way that is reversible.
I modified an old 'F' board with the
DSL mod, and it was easy and went off
without a hitch. The mod is reversible.
When I got the RGS board, it was for a
CoCo 2. My CoCo 2 had the 64K
RAMs soldered in! This would have
made doing the DSL modification very
difficult. You would have to remove the
64K RAMs and put in sockets. If you
have a 16K CoCo 2 that was upgraded
to 64K. then you should have sockets
for the RAM chips. The only ones that
didn't were the 64K CoCo 2s.
1 heard from Bob Rosen at Spectrum
Projects that there was a new board in
the CoCo 2 that was different from my
board. He said that it was smaller and
that the chips were in different places.
I would suggest that you open your
CoCo case and find out what revision
board you have. Also note if the SAM
(74LS83) and the 74LS244 are soldered
in or in sockets. In my system the
74LS244 was soldered and 1 cut the pins
from the chip and soldered a socket to
those pins for the upgrade. (This was for
the RGS upgrade.)
After you have this done, and with
the open computer in front of you, call
the company you wish to do business
with and tell them what you have. This
way, you will save yourself and them a
lot of trouble.
The keyboard on my CoCo 2 had a
small metal ledge that interfered with
the RGS board. They are working on
the problem, so check with them or
DSL about your computer. As time
goes by, these little difficulties will be
worked out as they have been in the
past.
It is not difficult to do this upgrade
and the results are well worth it. Tune in
next month for part two.
New Fix For DynaForm
We came up with a new fix for using
DynaForm with printers that produce
their own line feeds when they receive a
carriage return.
Problem: DynaForm was designed to
create boldface, underline, and double
strike by controlling the carriage returns
and line feeds of the printer. To do bold-
face for example, DynaForm will print
the line normally, then print a carriage
288
THE RAINBOW
December 1984
return, ihen the word or words that are
to be boldfaced. This is repeated four
times for boldface, two times for double
strike, and for underline it just prints an
underline. Because of this, DynaForm
requires a printer that does not produce
a line feed when it gets a carriage return
from the computer. This flies in the face
of Radio Shack OS-9's standard of
doing just the opposite. We printed a
quick fix that filtered the output of
DynaForm to strip any line feeds, but
this was a pain to use and did not work
on the CoCo for some reason.
New Solution — while you are wait-
ing for the new release of DynaForm
that will really fix this and, by the way,
make several improvements, we have
discovered a better temporary fix that
works . . . almost.
While talking to a user on the phone,
it dawned on me that we could probably
just null out the line feed in DynaForm
to cure the problem. This had the ad-
vantage of being user-fixable with debug.
Hot on the trail, I dug out the listing of
DynaForm and started to look for the
line feed variable. It turned up at offset
S0FE1. Just change the S8A to a S80
and we're set. Well, it didn't quite work,
so back to the listing, where 1 found
DynaForm was sending a bunch of line
feeds to bring it to the bottom of the
page. Change this to a carriage return
and we are all set — almost. Changed
offset $0530 from a $27 to a $28 and
tried it again. Here is where the 'almost'
came in. Everything worked fine, but
the pages were short by two lines. Well,
after going blind and getting sleepy, I
decided to be lazy and just tell you to
put '.PL 68' in your file to accommodate
the lost two lines, and it would work. It
is not as elegant as I would like, but we
should have the new DynaForm in a
month or so, and this was just going to
be a quick fix anyway, and 1 was getting
tired, and on and on. Anyway, here is
the procedure for the fix.

Printer Control Characters
DynaStar and DynaForm support
embedded control codes, but we did not
do a good enough job of telling you how
to use them in the manual, so let me go
over it here.
DynaStar has a special feature that is
invoked by typing a control P. When
you do this, DynaStar waits for a con-
trol character to be typed by you. If you
don't type a control character, then
DynaStar thinks you want to cancel the
operation and goes back to whatever it
was doing. Suppose you wanted to send
the control code SID to your printer.
SID is a control ] (that is, control key
and a closing bracket), so in DynaStar
type a control P and a control ]. You
will sec a funny triangle-shaped charac-
ter followed by a ']'. This is the indicator
that you have embedded a control ] in
the text file.
When DynaForm processes the file, it
looks for that funny triangle (a S80 by
the way), and when it sees it, it knows
that the next character is a control char-
acter that is to be sent to the printer,
which it does. You have to precede each
control character with a control P. and
if you need to send regular characters
after the control character, then just
type them in. For instance, if you wanted
to send a ESC then a 'p' then a control Q
to your printer, you would type control
P, ESC, p, control P. control Q. It
would look like this on the screen (Sub-
stitute ' A ' for the triangle):
A [P A Q
Get the picture? Play with it for
awhile, and you will see that you can do
just about anything with this feature.
Disk Drive Advice
At the Princeton RAINBOWfest, we
were swamped with questions about
what type of disk drives to buy. The
choices are getting very complicated,
and the prices are getting very low. I was
talking to Bob Phillips at Gimix, and he
told me that there were 35 Japanese disk
drive manufacturers in the market. The
competition is fierce, and this means
that prices have dropped to the point
that anyone can afford to buy any kind
of drive they might want. As an example
of this, we are buying 80-track, double-
sided, half-height drives, guaranteed by
the manufacturer for one year, for less
than we were buying single-sided, 40-
track. full-size drives six months ago.
When you look at how the prices have
dropped, you might decide to wait and
see if they are going to drop any more. 1
have been told by people in the know
that even the Japanese cannot make
drives at these prices for long, and that
as soon as inventories get back to nor-
mal, prices will either go up or stay at
this level. However, nobody really knows

THE RAINBOW
December 1984
for sure just what is going to happen.
The best thing to do is buy a name brand
drive from a company that will be
around lor awhile. You will want to get
service on the drive someday, although
at these prices they are almost dispos-
able.
What size? How many tracks? Single-
sided or double? Let me simplify this for
you. There are only a few differences
between the various drives available.
They are: Tracks per inch are either 48
or 96. The standard RS drive is 48tpi.
This also holds true for 40-track drives,
whether single-sided or double. The
number of tracks per inch is the same.
The 96tpi drives are usually referred to
as 80-track drives. Some companies
confuse the issue by calling double-
sided 40s, 80-track drives. But they also
call double-sided 80s, 160-track drives.
All 48tpi drives are compatible. You can
put a single-sided disk in a double-sided
drive, and it will read it. The other way
won't work, unless you formatted the
disk as single-sided. What this all means
is that double-sided, 40-track drives are
completely compatible with the stand-
ard Radio Shack drives and operating
system. You only gel complicated when
you get to the 96tpi.
The differences between single and
double-sided drives are as follows. Disk
BASIC reads and writes to one side of the
disk, 35 tracks. It really doesn't matter
what type of drive you have in the sys-
tem; it will treat it as a single-sided,
35-track disk. This means that all drives
will work, but that anything over 35-
track. single-sided will be of little use to
you if all you use is Disk BASIC. (RAIN-
BOW printed patches to Disk BASIC to
use the other side and 40 tracks in a past
issue.) If you use FLEX, then it will use
any drive currently on the market to its
fullest. If you use OS-9, then you will
need either SDisk from D.P. Johnson
or a similar program from Computer-
ware or other vendors.
My personal favorite is two half-
height, double-sided. 40-track drives, in
a single vertical case. The price drop on
the 80s would make me consider them,
but if I did, I would have to keep a 35 or
40 around for copying files to and from
standard Radio Shack disks.
Here are some storage comparisons
with OS-9 disks:
SS RS 35 track 630 sectors
SS 40 track 720 sectors
DS 40 track 1.440 sectors
DS 80 track
2,880 sectors
This shows that a double-sided 80 has
over four-and-a-half times the storage
as the standard RS disk. Three of these
can be put on the system for a total of
8,640 sectors, or over 2 megabytes of
storage! By comparison, four Radio
Shack drives have only 2,520 sectors, or
6/ 10 of a megabyte. If you compare the
cost per byte of storage, the 80s come
out the best, but the inconvenience may
not be worth it. That is why I like the DS
40s. Plenty of room plus compatibility.
What about hard disks? RGS is sup-
posed to be getting a hard disk for us to
play with; Dale Puckett is doing a
review and then we gel to try it. I guess
how soon we get it will depend on how
much Dale likes it. 1 will let you know.
Thai's it for this column. I have been
spending my summer sailing and driv-
ing a bulldozer over land that will have
our new log home on it next year if the
banks cooperate. Because of this, I have
been lax in writing my column. The next
few columns on the 128K upgrades
should be a lot of fun to do and read, so
I hope that I am forgiven for playing in
the sun instead of with my CoCo.

PERSONABLE PASCAL
What Goes In
Must Come Out
By Daniel Adams Eastham
Rainbow Contributing Editor
Getting data into the computer
and the results back out is a
problem that every program
must tackle. Where this problem is
solved is usually split somewhere be-
tween the programming language and
operating system. Some programming
languages like ALGOL and c don't even
have I/O (short for Input, Output) de-
fined as part of the language. Others,
like ADA, incorporate everything you
need including I/O and multitasking
right in the language. PASCAL, on the
other hand, is somewhere in between
with a small I/O interface defined as
part of the language.
Files
The primary language element for
supporting 1 / O is the file. A file is a data
structure (type) which is very similar to
an array. An array is a fixed sized collec-
tion of similar data types which can be
accessed in any order(randomly). A file
is a variable sized collection of similar
data types which can only be accessed in
(Daniel Eastham holds a B.S. in com-
puter science and has 13 years experi-
ence in systems and communications
programming including work on the
original Telenet packet switching net-
work. He is the author of the DEFT
Pascal Workbench and is currently presi-
dent of Deft Systems. Inc.)
one order (sequentially). For example:
VAR MyFile: ULEOF Real:
This statement declares a variable
MyFile as a file of real numbers. You
notice that there is no indication of the
number of real numbers in this file. You
can make a file of any type except for a
type which is itself a file or contains a
file. For example:
VAR MyData : FILE OF RECORD
Name : Siring (30):
Addr: String (50);
Zip : Real:
END;
In practice, you would usually declare
a specific type with a TYPE statement
and then declare a file variable of that
type's name. For example:
TYPE MyDaiaType: RECORD
Name: Siring (30):
Addr: Siring (50);
Zip : Real:
END;
VAR MyData: FILE OF MyDaiaType
Creating And Putting Data Into A File
Before accessing the file, you need to
specify whether you will be putting data
into it or getting data from it. For
example:
REWRITE (MyFile.MYREALS DAT: I •);
This statement causes the following
sequence of events to occur:
1) If the file MYREALSI DAT on
disk drive I existed before, it is
now killed.
2) A new, empty file MY REALS I
DAT is created on disk drive 1.
3) The file variable MyFile is asso-
ciated with the disk file M Y REALS
I DAT on disk drive 1.
4) The file variable MyFile is put into
a write-only mode.
Once you have done this, you are
ready to add elements to this empty file.
Although a file is made of (possibly) a
large number of elements, you can only
access one at a time. This is done by
using the file variable name followed by
the circumflex, or up arrow ( A ). For
example:
MyFile* :=23.5;
This statement causes the real value
23.5 to be placed in the current element
of MyFile. Once you have placed this
value in the current element, you are
ready to advance to the next element.
This is done with the Put procedure as
follows:
Put (MyFile):
294
THE RAINBOW December 1984
This causes the current element to be
added to MyFile with the current ele-
ment then becoming undefined. You
continue to assign values to the current
element of the file and add that element
to the file until you have placed all the
data that you want into the file. At this
point you will need to close the file.
Close (MyFile);
Although standard pascal does not
include a close procedure, many PAS-
CALS (including DEFT PASCAL) require
one in order to ensure that all data has
been written to the disk and that the
disk directory has been updated. A final
example shows how to create a lile, put
three elements into it and then close the
file:
REWRlTF.(My Dale. 'NAMEADDR DAT):
MyData A .Name := 'John Doc":
MyData " .Addr := "Main Street':
MyData A . Zip := 12345:
Put (MyData):
MyData " .Name := 'Mary Jones':
MyData". Addr := 'Maple Avenue':
MyData A .Zip:= 54321;
Put (MyData):
MyData A . Name := 'Last Name":
MyData ".Addr := 'Last Address':
MyData A . Zip := I II II.
Put (MyData);
Close (MyData);
This example creates the file NAME
A DDR/ DA T on disk drive and puts
three records on the file. You can see
that once you have dereferenced the file
variable, it acts just like a regular vari-
able of the file's type.
Reading An Existing File
Once we have created a file, we will
want to go back and read it. First we
must RESET the file as follows:
RESET (MyFile. 'MYREALS, DAT : I');
This statement causes the following
sequence of events to occur:
1) The file variable MyFile is asso-
ciated with the disk file M YREA LS
I DAT on disk drive I.
2) The file variable MyFile is put into
a read-only mode.
3) The file variable MyFile is posi-
tioned to the beginning of the file
MYREALS/ DA Tan disk drive I
and the first element of the disk
file is transferred to the file vari-
able MyFile.
Once we have done this, we are ready
to read data from the file, one element at
a time. In fact, the first element of the
file has already been read into the file
variable as a result of the reset state-
ment. To access it. you merely derefer-
ence the file variable with the circumflex
or up arrow ( A ). For example:
Total := Total + MyFile A :
This adds the current element of the
file to the variable Total. To position to
the next clement of the file you use the
Get procedure:
Get (MyFile);
For example, suppose we had three
elements in the file MYREALS; DAT
and wanted to add them up. We could
use the following code:
I otal := 0.0:
FOR I := I TO 3 DO BEGIN
Total := Total + MyFile A ;
Gel (MyFile);
END;
But suppose we didn't know how
many elements were in the file MY
REA LS/ DA T1 In this case, you use the
built-in function EOF (End Of File) to
test whether there are more elements in
the file. For example:
Total := 0.0;
WHILE NOT EOF (MyFile) DO BEGIN
Total := Total + MyFile";
Get (MyFile);
END:
This code allows you to total all the
numbers in the file no matter how many
there are (even if the file is empty!).
When the EOF function bccomesTRUE,
the current element in the file variable
becomes undefined. This means that if
you RESET an empty file, the current
element is undefined and the EOF func-
tion is TRUE immediately afterward.
READ and WRITE
Because you frequently have the se-
quence:
variable := filevar A ;
Get (filevar);
PASCAL has a READ statement which
collapses these two statements into one.
For example:
READ (filevar. variable);
READ (filevar. varl. Nar2. vur3):
The first statement is equivalent to
the two statement examples above. The
second statement is equivalent to:
READ (filevar. varl);
READ (filevar. var2):
READ (filevar. var3):
In addition, there is also a WRITE
statement which does for PUT what
READ does for GET. For example:
filevar A := variable;
Put (Filevar);
is equivalent to:
WRITE (lilevar. variable):
You can also use multiple arguments
just like on the READ.
Text Files
There is a special pre-defined file type
text which is frequently used in PASCAL.
It is defined as follows:
TYPE Text = FILE OF Char:
Text files are standard ASCII files on
disk and cassette and they are also used
to represent the keyboard, screen and
printer. While you would normally only
be able to access individual characters
in such a file, text files arc also thought
of as containing lines and you can access
integers and reals as well as characters.
This is done by extending the capabili-
ties of READ and WRITE statements
and adding READLN. WRITELN and
EOLN to the language.
There are two pre-defined text files
that vou have been using all along. They
are INPUT and OUTPUT. When you
don't specify a file variable in a GET,
READ, READLN. EOFor EOLN state-
ment, the compiler assumes that you are
using the INPUT text file. When you
don't specify a file variable in a PUT,
WRITE. WRITELN, CLOSE or PAGE
statement, the compiler assumes that
you are using the OUTPUT text file.
These files are normally automatically
initialized as follows:
RESET (INPUT. :-3);
REWRITE (OUTPUT. ':-3);
When using DEFT PASCAL, it is not
recommended that you use RESET or
REWRITE with the INPUT or OUT-
PUT text files since certain optimizing
assumptions have been made about
these files.
December 1984 THE RAINBOW 295
READ And READLN
When using READ with a text file,
you can specify integer, real and Boo-
lean variables as well as character vari-
ables. When you do this, the file is
scanned a character at a time, looking
for the next legal integer or real number
representation in ASCII (in DEFT
PASCAL, Booleans are read as or 1).
When it is found, it is converted to the
corresponding internal binary value and
stored in the specified variable. If you
have more than one variable in the
READ statement, this process is re-
peated for each one. For example:
READHextFileVar, I, R, CharVar):
This statement scans the file asso-
ciated with TextFileVar for an integer
(1) then a real (R). After that, the next
character is put in CharVar. Note that
scanning continues until all variables
have been filled even if it means scan-
ning more than one line.
The READLN statement is exactly
the same as the READ statement except
that after all the variables have been
filled, scanning continues until an End
Of Line character has been read. The
current element (character) of the file
will then be the character following the
End Of Line character.
DEFT pascal also allows you to
read an enumerated type as though it is
an integer and to read into a variable
length string. All the characters encoun-
tered until either the string is filled oran
End Of Line character is encountered
are stored in the string. It is recom-
mended that you use READLN to read
string variables.
EOLN
The EOLN function is used to test
whether the current element of the text
file (next character to be read with a
READ or READLN) is the End Of
Line character. For example:
WHILE NOTEOF(TextFile) DO BEGIN
WHILE NOT EOLN (TextFile) DO BE-
GIN
READ (TextFile. CharVar):
... do character stuff
END:
READLN (TextFile);
... do line stuff
END:
In this example, the outer WHILE
loop executes once per line. The READ
LN statement is used to skip over the
End Of Line character (a carriage return
in DEFT PASCAL).
WRITE and WRITELN
Like the READand READLN state-
ments, you can use Booleans, integers,
reals and strings (as well as enumerated
types) in WRITEand WRITELN state-
ments with text files. In fact, when using
text files, you can use full expressions as
arguments to these statements. For ex-
ample:
WRITE (TextFile. 'THE ANSWER IS \
R*l):
This puts each character of the string
THE ANSWER IS' to the file Text File
and then converts the product of R and
I to ASCII and puts each character of
the result to the same file. Each argu-
ment in a WRITE statement can have
an optional field width specification as
follows:
WRITE (TextFile. THE ANSWER IS ': 15.
R*I:I0):
The colon following the argument
indicates that you want to specify an
296
THE RAINBOW December 1984
explicit field width rather than allowing
it to default. In the above example, the
string is padded on the right with an
extra blank (in standard pascal the
padding is on the left) and the real
expression is printed with more signifi-
cant digits. The default width is one for
characters, a string's actual length, eight
for reals and six for everything else. In
addition to a width, you can specify a
number of fractional digits for real
values by adding a second colon and
value:
WRITE (TexiFile. -THE ANSWER IS": 15.
R*I:I0:5);
In this case, the final real value is
printed with a sign, up to three leading
digits, a decimal point and five digits to
the right of the decimal. If you do not
specify the number of fractional digits,
scientific notation is used.
Example Program
This month's program manages a
Christmas gift list. It lets you create,
update and print a list of names, gifts
and budgeted amounts. The list is made
up of a number of elements of type
Member.
The program operates by providing a
menu of operations you can perform:
XMAS LIST PROGRAM
R —
READ LIST
W —
WRITE LIST
U —
UPDATE LIST
A -
ADD TO LIST
P -
PRINT LIST
Q -
QUIT
ENTER SELECTION:
When you select one, the program
invokes the corresponding procedure to
perform that operation. Read Members
prompts for a filename and then reads
that file into the array MemberData. It
uses the GET procedure to actually per-
form the reading. WriteMembers does
the reverse using the PUT procedure to
output all the data in MemberData to
the specified file. You will notice in both
the RESET and REWRITE statements
a third parameter. This parameter allows
you to specify a default filename exten-
sion to use if one is not present in the
second parameter.
The UpdateMembersand AddMem-
bers procedures let you make whatever
changes you wish to the information in
MemberData. MemberCount always
contains the number of members of
your list and TotalAmount contains the
total estimated amount of money you
will be spending.
The PrintMembcrs procedure prints
a formatted listing of the list on your
printer. The procedure makes extensive
use of the formatting capabilities of
PASCAL I/O.
If you have any questions about I/O
in PASCAL, you can call (301) 253-1300
during normal business hours for help.
Next month we will go into detail about
block structureand recursion in PASCAL.

Joining in the fun and excitement of
RAINBOWfest is a great way to get to
know the CoCo Community. Many of
those who write for the rainbow —and those
who are written about — attend CoCo's very
own show. It's a people-to-people event as
well as a valuable learning experience.
For the 1984-85 season, we've scheduled
three RAINBOWtests in three parts of the
country. If you missed the RAINBOWfest in
Princeton, N.J., why don't you make plans
now to be with us in Irvine, Calif., or Chi-
cago. III? Each show will offer fun, excite-
ment, new products, seminars and informa-
tion for your CoCo! And for those who
(perish the thought) don't like CoCo as
much as you. we've scheduled each RAIN-
BOWfest in an area that will provide fun and
enjoyment for the whole family.
Our Irvine, California, show is being held
at the Irvine Marriott Hotel, which offers
special rates for RAINBOWfest. The show
opens Friday evening with a 7 p.m. to 10
p.m. session. It's a daytime-only show Sat-
urday — the CoCo Community Breakfast is
at 8 a.m., then the exhibit hall opens
promptly at 10 a.m. and runs continuously
until 6 p.m. There will be no exhibition
hours or seminars Saturday evening. On
Sunday, the exhibit hall opens at 1 1 a.m.
and closes at 4 p.m.
Our highly popular CoCo Community
Breakfast will again feature a well-known
figure from the Color Computer Commun-
ity. And the exhibition will be interspaced

WITH X-TRA POWER
XTERM
XTERM is a full featured OS-9 communica-
tions program that takes full advantage of the
power of OS-9. It works with the normal text
screen, XSCREEN, or the Wordpak 80 column
board.
XTERM is menu oriented for ease of use,
it is simple to use even for the novice OS-9 user.
And yet, XTERM is powerful enough for the expert
OS-9 user.
Some of the features of XTERM include: full
upload and download support with remote buffer
operation; supports XON/XOFF protocol;
1 10/300/600/1200 baud, 5/6/7/8 bits, even/odd/no
parity, full or half duplex; able to execute an OS-9
shell command from within XTERM.
XTERM works with a Color Computer using
the standard serial interface, but also will work with
a hardware serial port. Also, if you are using a hard-
ware parallel printer port, you can print data to the
printer as it is received.
XTERM $59.95
XSCREEN creates a high resolution screen
for the Color Computer using OS-9. This high
resolution screen gives you 24 lines of text
with 51 , 64, or 85 characters per line. Characters
can be either white on a black background or
vice versa.
XSCREEN is very easy to use because it is
menu operated. No codes to memorize or manuals
to consult when you want to change character size,
just go to the menu.
XSCREEN $19.95
XWORD
XWORD is a powerful word processing system
